What do you think an H villain (or erotic works in general) needs to qualify as Complete Monsters or Pure Evil?
As we know in this type of work, rape is basically standard villainy, so one wonders what a villain would need to surpass standard villainy.?
One can think of things, that he plans to execute the heroine when he is done having fun with her, or that he plans to turn her into a slave for life, instead of just abusing her a few times.
