If you look at some of the horrifying things that a certain sort of people think up on their oddy nocky, you get some insight into why society came up with the idea of laws and morality and religion and such things in the first place.

Of course, in creating laws, etc, society gave some people power over others, which made it possible for a certain sort of people to do those horrifying things on a larger scale. But if you go and eliminate all the religion, and all the morality, and just as much of anything else as you want, and people are not going to behave any better.
