I believe the innate nature of man is goodness even though his capacity for evil is mind-boggling. The reason I believe this, is that goodness appears to prevail through the history of man and because of this omnipresent goodness our world, daily, becomes a better place because of it and humanity prospers in spite of the evil that promotes wars, conflicts, and personal atrocities committed against the peoples of this planet. In fact, I believe that the positive progress is so demonstrative that I envision a time when the evil aspects are not gotten rid of necessarily but diminished to advantageous levels through intervention and the affect essentially equates to heaven on earth.
However, Evil and nature are the catalysts of our progress we must not assume that evil and accidents should be eradicated in all future humans. It is neither practical or advantageous. How else do we progress if there exists no want or need? How worthless would life become if there were no possibility of frustration of improvement. Can we in fact become like gods creating worlds with no contrasting elements. Even God allows evil to exist and created a temporal existence where change and uncertainty coexist with perfection and truth.
