He is gonna kill him by a ''mistake'' then? I understand that he doesn't like Kanou for what he had done to Ayase, but instead of trying to build relationship with him he is just going to kill Kanou and what? Force himself on Ayase? At least be on his side and protect him to the very end, why does he have to side with that bastard.
And about being harsh with him, we don't know what is gonna happen and it's only reasonable to be harsh with a person who is being a dick at the moment. We are commenting on the current chapters.

Of course Kuba is going to force himself on Ayase if he were able to kill Kanou (NOT gonna happen).
Ayase is victim material. If not raped and violated by Kanou, then Kuba will do it.
Kuba has violent fantasies already about Ayase. You thnk he wouldn't act on those fantasies given half the chance?
I can at least credit Kanou for admitting and accepting that he's a shitty person and not being shitty sometimes. Kuba is one of those annoying "nice guys" that complains that girls only go for jerks while being every bit as bad or worse than the jerks they criticize.
