I'm going to go ahead and argue that, in spite of every crappy thing in that version of the setting, divine grace still wins. Because classical liberalism is an Elder God. (Warning, this is much longer than OP, but shorter than Hobbes.) I'm going to outsource my argument to Scott here, even though he has a very secular idea of what divine grace is. It doesn't matter how the dark and stupid the world is; cold hard reality itself stacks the cards in favor of reconciliation.

You might argue that Scott's post on Moloch would be the one that is more applicable, but it's not. At some point in a society of people with mostly good values, liberalism would take hold else they would lose the war forever. "Moloch is the demon god of Carthage. And there is only one thing we say to Carthage: 'Carthago delenda est.'"
