Let's say a super villain with a powerful amulet ruled the world. This guy will not hurt the innocent, only the guilty. He allows everyone to carry on their lives like normal, BUT if you commit a serious crime, you will be punished severely. There will be no more racism, stealing, and violence. Let's say this super villain can read minds around the world (telekinetic powers). If you even THINK about committing a crime, he will make your head explode with just a thought.
Criminals would be too scared to commit crimes. Seriously, would you be crazy enough to screw with a powerful god like man? Sure people can rebel and throw tomatoes, but they will be in serious trouble.
