Cannibals emphatically do not think they are acting morally. They are getting their rocks off over the fact that they don't have to and they know it. Subjective vantages have nothing to do with it, either - morality is not an opinion. Nor is it first created by religion - on the contrary, religion presupposes the direct perceptibility and knowability of moral goodness. Or is there a man among you who when his son asks for bread, would give him a stone?

Suppose the son had just blown up a loaded school bus?

The rock would be the moral reply.
