Humans adapt to the moral system of their society. There is no set of "universal morals" that all humans have.

But do realise this, since I'm not a moral relativity apologist. I'm going to say that moral systems are not equal and some backward societies need to get their systems fixed.

Have you read the god delusion by Dawkins? There he takes on just that myth - there has been a very good body of research in presenting people with the same set of moral conundrums - every race and culture, even "primitive" have indistinguishable moral responses. (Obviously individual variance was high)

Worth a read.

There is no set of "universal morals" that all humans have.

What about « If "everybody" (who I identify with to at least such-and-such a degree) did X, would it harm me or my family/descendants? »?
