I think in manga Fedor’s death would be more beautiful. I think it’s the best way he can die. He made VERY STUPID mistake, it shows that he is not “gods envoy”, he is an ordinary person.And it shows that Fedor’s main weakness that he don’t trust to anyone, like Dazai, who has many “random cards”
And it’s also great for Gogol’s grown! I think we will see something like backstory or something
Fedor is antagonist that need to be dead. If he will stay alive, it will not end good
So I wait manga to see his die in it, I think Bones cut something 100%
