Evolved Morality, Part Ii

...To me it seems morality is what holds us back from the edge, what keeps us from just destroying, and leaving all enemies dead. But more and more I think that it was not some product of our mind, but a product of evolution that developed slowly with time. Since no predator can stop us, since we defeat even disease, did we evolve our moral sense to check those who act viciously? Were the ones who killed unrestrained killed off by their own aggression? Were those first real moral stirrings what kept folks from being undone? Were the humans who lacked such thoughts winnowed down, soon too few to breed? Did evolution select those able to resist killer creeds? Is that why so few people now have those brute, psychopathic brains? Are those people just leftovers, from a strategy now disdained? If so, it means our moral codes, are not something we made ourselves, but just evolution’s response to minds that can make living hell. It wasn’t some higher calling that kept us all from being wrecked, morality is nature’s way of keeping our species in check.
