Post Christianity

Nietzsche said that God is Dead, and that people had not reckoned with with the consequences of that. Additionally he and other's predicted that people could not be good in the absence of religion. This has proved to be incorrect, there are plenty of atheists who are good people. But how has civilization fared. Is it possible that Nietzsche and the rest were just premature in their pessimism? That the current culture war is so fierce because we don't have a common set of values to negotiate around?
