"Some" historical reasons...
1) anything that divides us from others
Race
Religion
Political Ideology
Class (wealth)
...
2) comparing ourselves to others
Coveting
Greed
Envy
...
Man didn't evolve and is not evolving. Our collective knowledge base has grown throughout history but man is as man was. We have adapted from reliance on physical attributes to reliance on mental prowess. But man has not changed. Essentially man does today what he always has. He just uses new methods and tools do it.
Belief in a higher being (God, Allah, Mother Nature, The Cosmos, your ancestors...) does not cause man to do evil things. Man in and of himself is corrupt. Man causes man to do evil. We may have moderate success learning to control our corrupt nature but we will not "evolve" beyond it.
Any others??
