I don't. I am not about unnecessary drama in a relationship.
Maybe some girls like them because they themselves have a rebellious side.
Maybe some girls   more...like them because they think they can change them (ha!) If you're gonna be with someone, you have to assume they are going to be how they are for the rest of their life. The question is: can you live with that person forever the way they are, the good the bad and the worst?
Maybe some of the girls have low self esteem so they think thats all they can get, or all they deserve.
Maybe some girls are naive and don't know any better.

A wise woman won't go there because she doesn't want a bad boy, she wants a man. :)  less
