"Imagine that suddenly monsters have attacked you home and the bastards with smug expressions on their face, kill your friends, kill your family and plunder. There's no way you'd be able to forgive that. You pick up a weapon think and mature, for now you move just to get even. You find them corner them fight them, ambush them, and kill and kill and keep on killing. And eventually you come to enjoy it"
