‘Understanding is the first step to acceptance, and only with acceptance can there be recovery.' - Dumbledore, GOF.

Severus couldn't understand why he was the one to be punished for the werewolf 'prank' and the others got away with it and couldn't accept it. Severus Snape never recovered 'cause he couldn't understand and accept what happened.

Lily and James would never have died if he was secret keeper. So he is correct in saying it's his fault they died, he and Snape. Cos he chickened out of being SK!

If he was so prepared to die for them, never tell, then why not be SK?

Both men acted differently.

Sirius: took the law in his own hands and went after Peter, getting 12 Muggles killed and landing himself in Azkaban for 12 yrs.

Snape: Turned spy, putting himself in constant danger to help avenge Voldemort and bring him down.

We aren't our mistakes, it's what we do about them is who we really are.

Snape fucked up and he did everything he could to try and redeem his actions, to protect everyone he could from that moment on, that Lily didn't die in vain.

Sirius fucked up and chose murder. TWICE. Only stopping because Peter outwitted him and again when 13 yr old stepped in.

A petty grudge is someone stealing your sandwich and you holding it against them for the rest of your life. Not attempted murder and then sexual harassment/humiliation - that is not a petty grudge. it is a very valid grudge. No one would get over that, NO ONE.

sick and tired of ppl saying james was a bully like okay ?? he bullied snape ?? the same guy who used wizard slurs AND threatened children ?? he kept petty grudges into adulthood like ur point ??

I don't care what anyone says or calls me, but, imo,

Harry DESERVED it! How DARE he!

How can anyone justify Harry doing this I don't know, even if they hate Snape! And I've seen a few. I think my favourite one ever was, 'Snape shouldn't have left the pensive out.'

What, like the girl who was r@p3d shouldn't have worn a short skirt?

And Harry's age is void here! He is old enough to know right from wrong. Old enough to know what he is doing hold consequences. Old enough to consciously make that choice by himself knowing he shouldn't do it but did it anyway.

Snape's rage after Harry seeing his memories in the pensieve is ominous in the movie but

Book!Snape had me scared af

71) Because, when headmaster, he protected the students to the best of his abilities.

Why do we love Snape, or the character who was unkindly written

Claire Jordan in one of her Quora essays said that she’s been in fandom for decades and has never seen a character so loved as Snape. I concur. Excluding some recent trends that purposefully misinterpret Snape by projecting onto him a set of stereotypes he was never supposed to embody, Snape remains one of the most loved characters in the Harry Potter universe. Every poll on Harry Potter’s favourite characters confirm that Snape is always on the top 3, sometimes reaching first place.

This is not some “bad boy syndrome”. There are two main reasons for readers to have latched onto Snape so furiously, for Snape to have been so ardently discussed and defended after HBP – and these feelings only intensified after the 7th book. The reasons, I would posit, are:

1.      Snape is a character that the narrative portrays as ambiguous.

2.      Despite this, the narrative is often, objectively, unfair to Snape especially in favour of other characters.

Let’s address the first point. Snape is ambiguous because he has to be. There are two big plot-twists in Harry Potter: Harry is a horcrux and Snape’s loyalties. These two end up closely connected because it is through the knowledge of Snape’s loyalties that Harry discovers he must die to kill the part of Voldemort that is inside him. Snape is therefore largely written as a suspect in a murder mystery. Several commentators have argued that the structure of a Harry Potter book resembles a crime novel, and I agree. Snape has to appear guilty, but the books have to give enough clues to the reader as to his true loyalties. Independently of authorial intent, this is what makes Snape so compelling. Because:

a.      Snape is cruel to his students but he constantly protects them (Harry, Draco, Katie Bell, Luna and Hermione, Neville and Ginny).

b.      Snape is described as ugly but his use of language is the most sophisticated of the series to the point it becomes sensual. Just consider his first speech in class about the beauty of potions and how they “ensnare the senses” and “bewitch the mind”.

c.      Snape is mean and petty but these characteristics are often accompanied by sarcasm and irony which make some of his most awful comments quite funny, such as him telling Crabbe not to suffocate Neville because he would have to mention it in a reference letter if ever Crabbe applied to a job. There is also a lot of incongruent humour in play with Snape. For example, him reading about Harry’s love life is hilarious because Snape and teenage drama are two irreconcilable dimensions.

d.      Snape is cruel and bullying but the narrative offers several reasons for this. While Dumbledore’s past is revealed mostly through conversation, Snape’s past is slowly revealed in images which make it much more vivid. Snape getting a glimpse of a werewolf at the end of a tunnel. Snape’s father yelling at his cowering mother. Snape upside down and petrified by Sirius and James. Petunia calling him “an awful boy”. More than any other character, Snape is rooted in a social context that brings with it inescapable references: poverty, domestic abuse, neglect, bullying.

e.      Snape is unattractive in practically all ways but he is also given the title of “Prince”. He is also one of the characters who carries a sword, and whose love is presented as “the best part” of him. These are characteristics that ennoble Snape.

f.       Snape is dismissive of people’s feelings but he is also the character who is defending children because of their mothers. Lily because of his guilt, and Narcissa whom he allows to trap him in an unbreakable vow to protect her son.  

g.      Snape is taken as evil but the character whom the narrator uses as a morality mouthpiece – Hermione – often defends him.

h.      Snape kills a man but the narrative is quick to add that his soul would likely remain intact as it would be an act of mercy, arranged between the victim and the perpetrator as Harry reinforces. Harry goes as far saying that Snape “finished him” instead of using the verb kill or murder. Furthermore, we know remorse is something that mends the soul and Snape’s whole arch is about guilt and remorse – immortalized in the scene where Snape weeps at 13 Grimmauld Palace.

i.       Snape is apparently a murderer but the narrative goes to some lengths to show that just like Harry Snape has a thing for saving people. “Lately, only those I could not save” and him risking his cover to save Lupin.

j.       Snape’s trauma is often discredited but the narrative allows part of his tragedy to come at the expense of the hero’s father whom Harry spent years admiring. A relevant part of James’s goodness is sacrificed in favour of Snape’s own character construction.

k.      Snape’s trauma in relation to having been bullied is more often discredited by the narrative, although Fudge’s comment “the man is quite unbalanced” and the comparison established between James and Sirius’s use of Levicorpus and the Death Eaters using it on a muggle woman shows that it is something to be taken serious, although never acknowledged.

This last point leads me to my second assertion that the narrative is fundamentally unfair and cruel to Snape. For two main reasons:

a.      Snape’s trauma in relation to the Mauraders is discredited by everyone that counts, namely, Lily and Dumbledore. Only Harry comes closer to understand its dimensions. We can argue as to why this is, and as to whether there was authorial intent or it is simply that JKR didn’t realise how it would sound. Lily nearly smiles when Snape is being bullied which puts in question Lily’s character as well as her friendship with Snape. Both in Snape’s Worst Memory and in the conversation about the prank, she also fails to show concern that her friend was being bullied by the boy she liked.

b.      The second instance of unfairness is more serious because it is far more insidious. A careful reading of text will tell us that Snape was set up for death by Dumbledore. That Dumbledore planted the Elder Wand on Snape while thinking its power had died with him and while knowing that Voldemort would eventually reach conclusions about the Elder Wand and wish to possess it, thus killing its current owner. Not only Dumbledore never tells Snape, but he plans it beforehand. This is why he “admits” to Harry that the intention was to let Snape have the wand. Harry understands exactly what this means, and in the Final Battle tells Voldemort that Dumbledore intended the power of the wand to die with him.

This is so insidious – and cruel – that it is never openly acknowledged. Dumbledore betrays Snape, showing an impressive disregard for his life – far more than he showed for Harry’s because he knew Harry had a good chance of survival. But Snape is never given the satisfaction of having this acknowledged in the text. Snape yearned for Dumbledore’s affection but not only Dumbledore denied him that, he also denied him the truth of what he really wanted of him. Snape is betrayed by both his masters at the end. But we are never explicitly told this. This happens because the narrative is unwilling to portray Dumbledore in a truly badly light. His apparent sorrow (“poor Severus”) and his “admission” of guilt are not enough to show him remorseful because the narrative cannot bring itself to say: “I set Snape to die by planting the wand on him so Voldemort would come to possess a useless weapon”. This would change the readers’ view of Dumbledore, especially after Prince’s Tale. Remark on how cruel it is: Snape had to agree to kill Dumbledore in “good faith” so the power of the wand died with him, but all the while Dumbledore knows that Snape would get a target on his back and die from it. Dumbledore manipulates Snape into – possibly – ripping his soul and tricks Snape into his own demise. Snape thought Dumbledore was raising Harry as a pig for slaughter, but he is wrong. It is him whom Dumbledore is raising to die. The fact that this is never openly stated, and is purposefully obfuscated by the language, is somewhat cowardly. Dumbledore barely apologises, he barely recognizes it. If he did, the readers would be horrified. As in the case of Lily, Snape is sacrificed in favour of apparently “better” characters whom the narrative wants the readers to like more.

However, the flaw in the plan is that…readers aren’t stupid. I caught on to this when I was a teenager, and it has only intensified as I grew older.

Even at the end, Snape understands from the moment Voldemort mentions the wand that he is going to die. JKR said in a tweet that Snape could’ve saved himself, presumably by setting Voldemort straight, and so his silence ensured Harry’s victory. It is a possible interpretation. More possible still is that Snape accepted death after giving Harry his memories. The fact that he stops trying to starch the bleeding once Harry appears shows it. His “look at me” is the request of a man who knows he’s going to die and just wants to do so by looking at the eyes of the woman he loves. In this sense, following Dumbledore’s words that “there are things far worse than death” and that for an organized mind death is “the next big adventure”, Snape showed far more courage than both Dumbledore and Voldemort who on several occasions tried to fight the inevitability of death.

It is true the narrative offers some vindication for Snape. Harry tells Tom Riddle of Snape’s true loyalties. Riddle is not allowed to die before knowing that Snape had betrayed him and colluded with Dumbledore, all because of a power Riddle doesn’t understand – love. Harry also names the son with his – and his mother’s – green eyes Severus. Finally, Harry tells him that Snape was probably the bravest man he knew.

But still, Snape is not kindly written. There is an underlying cruelty in how Snape is treated throughout the books. Because he is so profoundly unloved, because he is barely shown kindness and because no one ever takes responsibility for what happened to him, the readers feel compelled to do so. That, I think, explains why Snape is so widely loved, and why people are so ready to defend him in unprecedented ways.

Did you adjust for inflation? Harry Potter DH pt2 in 2011 took $1,342,359,942 which, in 2023 money, would be $2,092,846,189.94.

Barbie would only have this title if HP pt 2 was released in 2023 or close to 2023; not 12 years ago when cinema tickets cost nearly half the price of what they do now. Barbie still has to make a lot more to be equal to HP.

Barbie was a great movie, powerful for women. It certainly deserves its highest-grossing film of 2023 title.

It is also interesting that when you adjust for inflation, the top ten highest-grossing films ever 6 of those are before 1982 and only 3 in the 2000+

Why did Voldemort gain followers?

Everything is in the books, yet not a single time is the reason given as "Because they want Muggleborns dead." Many factors, most of which had nothing to do with their desire to murder Muggleborns, led those who sided with Voldemort to do so, and most (not all) of the time, it came down to supporting the side who could bid them a better life.

The side that treated them better.

Which should send a powerful message to its readers: if you treat someone badly, don't expect them to be on your side when you need them to.

[‘Anyway, this – this wizard, about twenty years ago now, started lookin’ fer followers. Got ’em, too – some were afraid, some just wanted a bit o’ his power, ’cause he was gettin’ himself power, all right’]

[‘Voldemort doesn’t march up to people’s houses and bang on their front doors, Harry. ‘He tricks, jinxes and blackmails them. He’s well-practised at operating in secret.’]

[“As he moved up the school, he gathered about him a group of dedicated friends; […] They were a motley collection; a mixture of the weak seeking protection, the ambitious seeking some shared glory, and the thuggish gravitating toward a leader who could show them more refined forms of cruelty.]

[J.K. Rowling: Given his (Snape’s) time over again he would not have become a Death Eater, but like many insecure, vulnerable people he craved membership of something big and powerful, something impressive.]

[‘Envoys to the giants?’ Fudge shrieked, finding his tongue again. ‘What madness is this?’ 

‘Extend them the hand of friendship, now, before it is too late,’ said Dumbledore, ‘or Voldemort will persuade them, as he did before, that he alone among wizards will give them their rights and their freedom!’]

 [‘I mean we soon found out he (giant) didn’ object ter all wizards – just us.

‘Death Eaters?’ said Harry quickly.

‘Yep,’ said Hagrid darkly. ‘Couple of ’em were visitin’ him ev’ry day, bringin’ gifts ter the Gurg, an’ he wasn’ dangling them upside down.’]

[‘They (Dementors) will not remain loyal to you, Fudge! Voldemort can offer them much more scope for their powers and their pleasures than you can! With the Dementors behind him, and his old supporters returned to him, you will be hard pressed to stop him regaining the sort of power he had thirteen years ago!’]

‘I’m sure they’d (goblins) never go over to You- Know- Who,’ said Mr Weasley, shaking his head. ‘They’ve suffered losses too; remember that goblin family he murdered last time, somewhere near Nottingham?’

‘I think it depends what they’re offered,’ said Lupin. ‘And I’m not talking about gold. If they’re offered the freedoms we’ve been denying them for centuries they’re going to be tempted.’]

 ["How come they (werewolves) like Voldemort?“

“They think that, under his rule, they will have a better life.']

Bloody hell, Harry is dramatic as fuck! A typical Snater.

Harry, chapter 26: The Second Task: [Snape loved taking points from Harry, and had certainly never missed an opportunity to give him punishments.]

Snape up until this point had taken a total of 47 points over four years (7-PS, 0-COS, 15-POA, 25-GOF) and Harry was given his first detention, his first punishment, from Snape in GOF.

Deathly Hallows Chapter 33: 

Snape: They sneak out at night. There’s something weird about that Lupin. Where does he keep going? Lily: He’s ill. They say he’s ill. Snape: Every month at the full moon?

4 Books earlier:

Ron: Still looks ill, doesn’t he? What d’you reckon’s the matter with him? There was a loud and impatient ‘tuh’ from behind them. Ron: And what are you tutting at us for? Hermione: Nothing. Ron: Yes, you were. I said I wonder what’s wrong with Lupin, and you – Hermione: Well, isn’t it obvious? Ron: If you don’t want to tell us, don’t. Hermione: Fine.

How is that any different to Snape hinting to his best friend? Trying to tell the truth without telling the truth. Wanting to keep Lily safe.

[severusforeverus]

Moody: I don’t like people who attack when their opponent's back’s turned. Stinking, cowardly, scummy thing to do.

James Potter: 

[severusforeverus]

Sirius says the following to Peter in the Shack:

“You haven’t been hiding from me for twelve years,” said Black. “You’ve been hiding from Voldemort’s old supporters. I heard things in Azkaban, Peter… They all think you’re dead, or you’d have to answer to them… I’ve heard them screaming all sorts of things in their sleep. Sounds like they think the double-crosser double-crossed them. Voldemort went to the Potters’ on your information… and Voldemort met his downfall there. And not all Voldemort’s supporters ended up in Azkaban, did they? There are still plenty out here, biding their time, pretending they’ve seen the error of their ways. If they ever got wind that you were still alive, Peter —”

Among the DEs in Azkaban, some of them knew Peter was the Potter’s Secret Keeper.

This introduces the possibility that Snape knew Peter was a Death Eater spying against the Order. This raises the question, did Snape know that Peter was the Secret Keeper? If he knew, that would mean he let Sirius “rot in Azkaban”, possibly because he hated him (for admittedly valid reasons). 

Again, all of the evidence indicates Snape didn't even know Peter was a spy, let alone the Potter’s Secret Keeper. The DE in Azkaban were not 18 year old newbie DEs, they were long serving DEs, as far back as when Tom Riddle was at school 

Also, Karkaroff said the Death Eaters were factioned, to minimise the chances that too many DE names would be given if a DE went to trial.

“You must understand,” said Karkaroff hurriedly, “that He-Who-Must-Not-Be-Named operated always in the greatest secrecy. . . . He preferred that we — I mean to say, his supporters — and I regret now, very deeply, that I ever counted myself among them —” 

“Get on with it,” sneered Moody. 

“— we never knew the names of every one of our fellows — He alone knew exactly who we all were —” 

“Which was a wise move, wasn’t it, as it prevented someone like you, Karkaroff, from turning all of them in,” muttered Moody. 

This is, admittedly, the same strategy used by Dumbledore.

Both Voldemort and Dumbledore, leaders of their respective camps, gave information to their followers on a need-to-know basis, particularly the mission-critical information. 

Voldemort didn’t tell his followers everyone’s identities or every mission, he didn’t tell anyone about his Horcruxes, and he only told a select few about his plan with Draco.

Dumbledore only told the Trio about the Horcruxes, he didn’t tell anyone that his own death was planned with Snape, and he didn’t tell anyone but Snape that Harry had to die. 

This ensured that in case one of their own was captured and interrogated by the other side, whatever information that person could give up was limited, as was the damage done to their respective causes. Logically speaking, it would be a supremely stupid idea for Voldemort to let his two spies in the Order know each other’s identity. If one of them got caught by the Ministry or the Order and was interrogated, they could offer up the name of the other spy in exchange for their amnesty, resulting in Voldemort losing both spies. War is won in large part based on intel, and Snape and Pettigrew were uniquely critical in their roles as spies in both wars. 

On Snape’s part, he defected from the winning side of a war. He was the one who gave Dumbledore the warning that Voldemort was after the Potters, as shown by Fudge’s comment and the Hilltop scene in Deathly Hallows.

“Not many people are aware that the Potters knew You-Know-Who was after them. Dumbledore, who was of course working tirelessly against You-Know-Who, had a number of useful spies. One of them tipped him off, and he alerted James and Lily at once. He advised them to go into hiding.” - Fudge, Ch 10 PoA

“Hide them all, then,” he croaked. “Keep her – them – safe. Please.” 

“And what will you give me in return, Severus?” 

“In – in return?” Snape gaped at Dumbledore, and Harry expected him to protest, but after a long moment he said, “Anything.”

He spied for Dumbledore for around a year in the first war, he promised "Anything" to Dumbledore if it would save the Potters. Giving “Anything” to Dumbledore just to try and protect Lily and her family, is not to be taken lightly. If he had been discovered by the Death Eaters as a traitor-spy, he likely would have been tortured, interrogated for whatever information he could provide, and killed. 

As Dumbledore confirms in Goblet of Fire:

“Severus Snape was indeed a Death Eater. However, he rejoined our side before Lord Voldemort’s downfall and turned spy for us, at great personal risk. He is now no more a Death Eater than I am.”

Or just look at what Sirius says in Order of the Phoenix:

“Well, you don’t just hand in your resignation to Voldemort. It’s a lifetime of service or death.”

And it’s confirmed again by Snape in Deathly Hallows:

“I have spied for you and lied for you, put myself in mortal danger for you.”

It is no hazard that Dumbledore stays silent for a long moment after Snape departs to contact Voldemort again at the end of Goblet of Fire; it might well be Snape’s last night, as Voldemort made it clear in the graveyard after his resurrection that he intended to kill Snape. 

Even Severus is afraid, though he still departs:

“Severus,” said Dumbledore, turning to Snape, “you know what I must ask you to do. If you are ready . . . if you are prepared...“

“I am,” said Snape. He looked slightly paler than usual, and his cold, black eyes glittered strangely. 

“Then good luck,” said Dumbledore, and he watched, with a trace of apprehension (fear) on his face, as Snape swept wordlessly after Sirius. 

It was several minutes before Dumbledore spoke again.

At the rebirth of Voldemort:

One, too cowardly to return... he will pay [Karkaroff]. One, who I believe has left me forever... he will be killed, of course... [Snape] and one, who remains my most faithful servant, and who has already reentered my service [Barty Crouch Junior].

It is only through skill, plan and luck that Snape survived that particular night:

“The Dark Lord’s initial displeasure at my lateness vanished entirely, I assure you, when I explained that I remained faithful, although Dumbledore thought I was his man. Yes, the Dark Lord thought that I had left him forever, but he was wrong.” 

Why would he risk torture and death by spying in order to save Lily in the First War, to honour her memory in the Second War… 

But then fail to tell Dumbledore that Peter was the spy if that information would save her life? 

This is unbelievably illogical.

Even if you believe that he only ever cared about Lily and himself, it makes NO sense that Snape would know Peter was a spy, the true Secret Keeper, and a potential threat to Lily’s life, and keep that information to himself, especially since he was already risking his life spying at this point. 

If Snape wanted revenge so much on his bullies, and if he knew that Peter Pettigrew was the spy, it would be in all of his interests to tell Dumbledore so that Pettigrew could be imprisoned and perhaps executed by the Aurors for being the spying traitor. Getting revenge on Peter Pettigrew and protecting Lily at once, that is what Severus would have done had he known Pettigrew was the traitor all along.

Realizing Snape almost certainly knew that Peter Pettigrew had joined Voldemort and just kept his mouth shut for 12 years out of spite while Sirius rotted in jail.
