Constant rape as a plot device, torture, and a lot of incel discourse like "the nature of women is to be subservient to men" and things like that. Not only this is a recurring thing but from time to time the supposed villain presents "reasons" for why he does it. And yeah, these are presented as if it were common sense.
It's weird how I see a lot of people trying to defend this as "it's refreshing to read something through the perspective of a villain". What? This has been done since old mythology. In this manga this is just an excuse to illustrate hateful speech all around.
