If no conditioning?

If no conditioning (assuming in no man's land)the environment will determine good or evil. Fill with food, water or need to hunt for food.

We just like other animal if without religion or moral guiding. 善 itself actually is against survival instinct which required many evil act as many moral principles that we know.

性本善 or 性本惡 are the concept when human started to build up their society, which humanity value come after that. However, it is good that we emphasize on humanity value, and show that we're evolving as human. Otherwise, we're no different from animal.     

IMO, human is egoist by nature but neutral in moral value. Evil or Kind are acquired development.  to a large extent, it depends on the social atmosphere or how our society developed. do you think we have more good than bad or bad than good If our society corrupted?
