True, but people still generally refer to that issue as 'anger management', as long as they act like a bully only when they're angry and when calm are quite different. I wouldn't be surprised if he's just acting like this whenever he's irritated by surroundings at the game. Natalie's assumption that there must be some underlying dissatisfaction that if solved could make him a peaceful person seems to betray way too little understanding of assholes like this.
