Its like all the bad guys are disgusting rapists like can't you think of other crimes????

I think the only one that wouldn’t do that is kyo because he seems like the type to go for the kill and not rape

Or be asexual. Or be a girl in disguise. Who knows what direction this will take? But Kyo does indeed seem to be mastermind and "finishe it" type, not "get hands dirty" with stuff like rape.
