Duane, the issue is that you are equating good and evil as natural human inclinations, that should neither be suppressed or embraced, but allowed to follow an unimpeded course derived from indiscriminate human action.
But, you fail to see the utter depravity of wickedness, and glorious virtue of altruism, compassion and love. They are not comparable, nor of equal efficacy and pragmatism.
Man's behaviour throughout history has delineated that there is a transcendent force acting upon him, that defies rationale and his natural environment. Although it's a veritable fact that man's intelligence is of greater capacity than any other creature on earth, his actions, inexplicably, prove otherwise. For what possible pragmatic reason, would a man smoke 3 packs of cigarettes a day, drink himself to death, or gamble his life away? He clearly is not following the course that natural selection would dictate. How is it possible that one derives pleasure from torturing others, raping someone, kidnapping, or committing genocide? On what grounds would someone despise another simply for the colour of their skin? What about all the wars, chemical and nuclear weapons?
Undeniably Duane, there are evil forces in the spiritual realms, that can make an extremely competent and rational being, turn into an utterly depraved, demented and inept, cowardly fool, that has become both indicative & definitive of mankind's behaviour throughout history. This is not a being acting in a symbiotic manner towards his fellow creatures, and his environment, as a purely secular universe would demand.
But not only is this spiritual dimension evident in evil behaviour, but also in acts of virtue. For there is no rhyme or reason either, as to why someone would give their life for another, donate to a cause, or help an old lady across the street, when there is circumstantially, no vested interest in doing so. And yet, it happens every day.
Can one honestly state that this is simply the universe unfolding in it's most natural and harmonious manner, that one would expect from a purely physical and material derivation? Or rather, can one actually deny that the world, society, mankind and anthropology, has proven that there is clearly a transcendent influence upon human beings, that has either raised him above and beyond what his rugged environment would dictate, or completely confounded, impeded and deranged his progress and development, as one who is a product of his universe?
Your proposal to let man just be man, without honouring and obeying his maker, reveals an ignorance in what man actually is, and the influences that act upon him.
