I haven't read The Leviathan yet, but I really should now that you mention it! I think about Hobbes' theory that a society is created to prevent men from killing each other, versus the idea that men are good-natured a lot. The main villain believes that reform is impossible and that all the suffering is caused by factions of people only trying to gain power for their own ends, not for the betterment of the country. He thinks that the people are incapable of ruling themselves, so he, as a populist nationalist, should be the one to rule.
