They do this because [even nice and intelligent] women are human horny, and do the very human horny thing of making mistakes and regretting them.

Bad/terrible people can be hot. In fact, often when people are hot they feel more free to be their natural asshole selves because they can get away with it more. This applies to both men and women in all directions.

In fact, some people want their partner to be mean to them, its more often hetero women who like that. If a guy can be mean and get away with it, that implies they’re hot shit, extremely confident, rich, and/or powerful. Those are attractive features in a guy.

There are also hetero men who want women to be mean to them, especially in the bedroom.
