刺し違���る sashichigaeru - This word is an expression used in traditional Japanese. In Japanese the term 'sashichigaru' refers to stabbing each other with a blade; it is a method of harming one person while risking harm to oneself or sacrificing one's life to kill the opponent. In essence, this indicates that while you may not emerge unscathed, you have the ability to wreak havoc on your opponent. So, to stab each other means that both you and the other person will die. This method is often employed as a desperate measure against a superior opponent. This word is often used in situations where people are accusing each other or disagreeing with each other or in a conflict. The origin of this word is not known, but it is believed to have originated in the world of swordsmanship and martial arts.

In swordsmanship training and warfare, it was necessary to read each other's attacks and skillfully avoid them in order to prevent oneself from being stabbed, while at the same time seeking to instantly stab through the opponent.

If I'm not mistaken this term was used by two people in the series, 1. Kakashi 2. Sakura

• Kakashi

KAKASHI: いくらあんたがあの三忍の一人でも...今のオレならアンタと差し違えることくらいは出来るぞ...!

ikura anta ga ano san nin no ichi nin demo ... ima no ore nara anta to sashichigaeru koto kurai wa dekiru zo ...!

Even if you're one of the three ninja... At least, I can kill you as you kill me/stab at each other...!

差し違える= kill each other/stabbing each other (or try to assasinate)　→　get fight back　→　both dead.

差し違える - It was originally used when a samurai charges towards an opponent with a sword or short sword. In such a case, you may be able to kill the other person, but there is a high possibility that the other person will also be able to kill you at the same time. It shows the determination that it doesn't matter. This is also a desperate strategy/tactic.

差し (sashi) not only means two people facing each other, but also ``present'' and ``send back''. It is used with verbs to emphasize the meaning or adjust the tone, such as in ``replace.''

刺し is a continuous form of 刺す. It is mainly used to mean to pierce something with a sharp point.

Even though he knew that if he had a fight with one of the Sannin, he would probably lose, but he felt the need to protect Sasuke from Orochimaru

But....

When Kakashi saw himself decapitated when he stood between Sasuke and Orochimaru:

ORO: やってみれば? できればだけど...

yattemireba ? dekireba da kedo ...

Why not try it? If you can, that is...

this expression could come across as dismissive. Using such expressions can come across as sarcastic and undermine the other person's confidence or abilities.

KAKASHI: ...くつ 刺し違える...!? バカか...オレは...!!!

ku....sashichigaeru...!? baka ka ...ore wa ...!!!

Ugh...Kill you as you kill me/stab at each other...!? Am I an idiot...!!!

くつ...!! - Uses when Someone probably noticed the impossibility to deal with something which is faced now unexpectedly.

Often, small sweat drops are drawn on the cheek of characters to make their expression appears more tense than normal. The more sweat drops there are, the stronger the anxiety or nervous.

Kakashi was initially confident in facing Orochimaru, but his confidence changed when Orochimaru released his killer intent.... it was enough to scare Kakashi

• Sakura

In 482, Sasuke was about to finish the job to kill his teammate karin when Sakura suddenly appears. In which case, Sasuke is already suspicious of her motives.

At first, Sakura lied about betraying Konoha. Second, she lied about joining Sasuke even though she was there to kill him. Third, she doesn't really care what Sasuke really wants and why he's doing this.

Her first remark about Sasuke is "He's completely changed"...well, yes...he's changed...but has she ever tried to figure out why he's changed???

She must have been in a hurry to get rid of Sasuke before others got rid of him first. [Sakura chose a sleeping gas bomb to put Kiba, Lee, and the others to sleep, and she left them there without even make sure that they were safe and not exposed to enemies. But...Kakashi was the one who carries Kiba and the others to a safe place]

Sasuke says, "Try to finish off Karin," and she quietly approaches Karin with a kunai to "stab Sasuke."

He saw through her lies and only see her as a "hated enemy of Konoha" now... rather than a former Team mate. He didn't even warn her but instead goes behind her back and wanted to finish her off. Sakura's eyes widened with shock and couldn't even run away (even though medical ninjas are supposed to be trained to avoid enemy attacks). I guess she never expected Sasuke to do something like that. It was Kakashi who was able to stop it just in the nick of time.

Even though she was told to stay out of the way, Sakura appeared again with a kunai in hand...but she fails to stab Sasuke. Twice.

Kakashi, who has decided to confront Sasuke, orders Naruto and Sakura to leave the place. Kakashi then interrupted Sakura's words... "Sasuke won't die from the poisoned kunai you learned from Shizune... He still has orochimaru's poison resistance..."

Specifically, he tells Sakura the realistic facts: "Sasuke won't die from your poison kunai. That poison won't work on Sasuke, so it's useless"

The fact that Sakura, a medical ninja, tried to kill Sasuke with a kunai...means it's easy to determine that the kunai was a poisoned kunai. "Poison" is a typical choice for a medical ninja. so the fact that Sakura chose "poison" is also evidence that she was "seriously thinking about getting rid of Sasuke."

In chapter 311, Sakura, who came to visit Kakashi at Konoha Hospital, said to him,

Sakura knew that Orochimaru might have been given drugs or some kind of forbidden jutsu to train Sasuke. Therefore, she should have known that "Sasuke might also immune to poison". Sakura herself had said that to Kakashi. So, Sakura naturally knows this but she chose the poison she had learned from Shizune to coat the kunai with to kill Sasuke. In general, even Kakashi knew that "Sasuke was resistant to poison," but... all of a sudden, she forgot all the facts she remembers and decided to kill Sasuke with just a Poisoned Kunai.

So Sakura's attempt to kill him would have been futile whether she stabbed him or not. Instead of bothering to find out why Sasuke suddenly acted like that, she concocts this plan where she lies about liking Naruto to get him to stop chasing Sasuke. She then drugs her comrades and leaves them unconscious in the forest and tries to stab Sasuke not once but twice with her poisoned kunai. Again, she fails to even come close to her own goals that she has set for herself. She constantly making a fool out of herself, crying pathetically and needing to be rescued. And She heard Naruto talking to Sasuke that Tobi had told him about "the truth about Itachi" and heard Sasuke ranting about how Konoha was responsible for his misery, but she never bothered to ask anyone about it.

In chapter 693, When Sasuke tells Naruto to come with him, we sees this angry look on her face and starts screaming about her feelings. However what's important to notice is this highlighted part when she is having this meltdown :

寄りそうことも刺し違えることもできずに...

yorisō koto mo sashichigaeru koto mo dekizu ni...

I can't get close to you or stab at each other...

I think she clearly referring to Naruto. Naruto is the only one who gets through to Sasuke, close to him, and he even said during the 5 Kage Summit that he'd bear the burden of Sasuke's hatred and they'd die together [double-suicide]. And Sakura is clearly upset. Sakura is also very telling of her jealousy of Naruto and Sasuke's bond. She knows Naruto can do things for Sasuke and get a reaction out of him, but she can't. Only Naruto could do these two things, not her. All this time all she could do was cry and beg.

Then Kakashi says that Sakura still loves him despite Sasuke trying to kill her, while conveniently omitting the fact that Sakura went there to kill Sasuke. Kakashi, who not only admits to not understand Sasuke, but he also clearly doesn't understand Sakura either. And She doesn't understand Sasuke either.
