I always get a kick out of it when a piece of fiction does the whole “If you kill him you’re just as bad as they say you are” or “If you kill him you’re just as bad as he is!” thing in the protagonist’s confrontation with the big bad after the character has already finished killing like three thousand nameless goons.
It’s made even funnier when the protagonist kills the guy in the middle of the speech and is like “i’m sorry, what were you talking about?”
