It is really important to distinguish a difference between a bad boy and a bastard abuser.
Bad boy: probably poor, doesn't follow rules because he thinks they are harmful, stifling etc. "I can't sit there all day when teachers don't give a shit whether I learn or not." Outbursts are at injustices, fights to defend. "Leave them alone/you're hurting them, leave!"
Bastard abuser: probably middle class or higher, doesn't follow rules because he thinks he's above them. "School if a waste of time, I can learn what I need from books." Outbursts are about things not going the way he wants then, fights to prove superiority or lay claim. "Stay off my turf/away from my girl."
Also, for their significant others, please learn the difference between being a nice compromising S.O and being a borderline or actually abused S.O.
Too many authors write the latter as though it's actually supposed to be romantic. It isn't.
