Then there's those (more than likely not in this case) that regardless want to do the wrong thing and get involved with shady types usually because of self esteem issues and the feeling they get of belonging.
I know of at least 2, that have come from good families with the right values/morals but persist in seeking the company of violent, abusive criminals and there's nothing no-one can say or do to change it either, believe me we've tried!
