He has no excuses for his behavior. Plenty of people have anger management problems. I use to, but I got over them. The very few times I still get mad, though, I never touch other people. I have a couple scars on my fingers from punching inanimate objects, instead. Even when I was younger, and I would occasionally act out violently, I would never do so against a girl. That's a rule that even lowlives often follow. You should send him to prison and see how long it takes him to get jumped by some punk on his high horse.
