Natural selection over thousands of years has favored aggressive individuals. They survived by the use of force and passed their genes to their children.
This was acceptable for a cave man but over time we have developed weapons of mass destruction, which have the capability of wiping out the human race. The aggression, which is encoded in our genes, is no longer an asset.
We must learn to use our intelligence to solve problems, not weapons of war. And this must start with each one of us.
