The beating part, if you are talking about actual beating, like punching a girl's ribs of something like that, you should definitely avoid those types of people.
The rape part, I believe that is rooted in the lust for power and dominance that is part of male nature. Like Oscar Wilde's quite "Everything in life is about sex, except sex which is about power". The problem is not that instinct itself, it is not having the virtues to regulate those instincts. So, you should look for guys who have those virtues.
