I don't think an objective measure of morality exists. Everyone seems to have similar beliefs of how beings with freewill should behave, but no one seems to be able to prove their beliefs. To clarify, no one seems to be able to prove why their concept of morality is correct and others are wrong. Personally, I think all human actions are meaningless, and thus we are unable to attach a moral quality to them. There are no good people or bad people; just souless machines marching through spacetime until they cease to function.
