I know they will kill Korosensei in the end, but keep in mind there is more than one meaning to the phrase "to kill someone."

Because those two are long-standing friends, I have confidence they won't let something like this ruin their friendship, but right now, at the moment, it feels like they won't make up. It's like the feeling at the beginning of the Kayano arc and the only way to be fully reassured is to just keep watching and see where it goes.
