According to the moral nihilists and atheists that are Christians, it was God who dictated what is objectively good, bad, ethical, and sociopathic cultural destruction.
So social conservatives are just upset that their authoritative God being is dead. Harsh but true.
That's pure melodrama. There is no God, so he can not die. Good and bad, right and wrong, are usually pretty obvious but people are greedy, weak, and stupid. 16% of the population can't comprehend morality and 50% struggle with the idea. After that it's context, willpower, and virtue. In a game theory sense most people are going to tend towards selfishness and pretend it's self-preservation. It's human behavior.
