It's astounding how many writers get this exactly backward. As animals, we simply are.. There are no value judgments to be applied beyond the fact that living seems better than dying. It's quite unremarkable that we are capable of evil. What is absolutely ASTOUNDING is that we are capable of thinking about it. Good and Evil is a strictly human preoccupation; it does not exist in nature without our very peculiar and rare brains. It's worth noting too that all creatures on earth are equally evolved. Therefore intelligent, moral creatures are a one in a billion long shot.
