AFAICT, you can draw some similarities to GTA. According to an article that I read trying to reason why the game is so popular, it was a way to channel your guilty pleasures with impunity. Whereas if you tried even half those stunts in real life, it wouldn't go so well. So GTA was just a way to act out your fantasies without bringing it into real life. Same here, some nobody acts out your wishes to beat someone down in the most vicious way possible without getting retaliated against. Smiles and sunshine all around at the end. Except for the victim, but he ain't real so it's fine.
