I wrote something recently, related at least partially to this topic. My essay included a discussion of ethics, morality, competition and conflict, wherein I tied these to one another, as integral parts of the 'human condition'. Morality comes from a general desire to control man's baser drives, and in response to his more-or-less universal gravitation towards pleasure and aversion to pain. It was, doubtless, floating around long before there was anything resembling a belief in 'voices, oracles, gods (and hallucinations)' [see: Julian Jaynes' THE ORIGIN OF CONSCIOUSNESS IN THE BREAKDOWN OF THE BICAMERAL MIND] This era/epoch was, in its turn, long before god with a capital G appeared on the scene. Religion, when duly organized, was intended to further distill and refine this control mechanism...like good Scotch or Bourbon. Sadly (or perhaps, naturally) there would always be those who would thumb their noses and stray from the fold. 'Morally bad people' have not yet absconded with the totality of the world. Could they? It has not happened yet, so I'm not worried. The notion that bad people will prevail, to the complete detriment and destruction of the good, while not impossible, is a stretch. If laws fail us, we can always strengthen them or enact better ones. This is what we do.
