He's got lots of mates all over the place: I'll never get away. What will he do when he gets out?" "Sometimes, just sometimes, I want to show these bullies what it's like to be a victim of violence" I empathise with that but just punching one of these tough guys a few times won't remotely approximate the suffering of their victims.
