Honestly, he's not a great guy, but to give him credit, he did find a healthy outlet for his violent urges. He looked for a place where his violence was acceptable, and he does his best to follow the rules of his environment. Long term, probably going to get in trouble if he doesn't learn to restrain himself, there's rules to the violence he's operating in, and its only going to be so long until he breaks them. Further, his choice in 'acceptable target' often involves punching up, not punching down. Still not a great habit, but speaks something to his character, though again, long term, going to cause real trouble. But I like how this series is showcasing the sort of 'healthy' ways fighting helps people in this series.
