I don't wanna start a fight, but ...

Why do people who read Yaoi with literally mafia bosses and demons, or even the devil himself as ml get shocked when they r*pe the mc. Like, they kill people without thinking twice, and you think they wouldn't r*pe someone?
And then y'all get mad at the authors, saying that they are psychopaths and shit.
I ain't pro r*pe but if the character is already shown as a bad character from the start, I will not be shocked if he does that too.
