Why fight

Since the beginning of history, humans have been fighting humans! This is human nature and because humanity has evolved this way it will never change. Christianity became rich during the Dark Ages in Europe by sending Christians out to raid other countries. This was called the Crusades, and millions were killed, but nobody cared, and the Christian Church got very rich doing this. During WW2 Hitler murdered millions of Jews, and the Pope said nothing. He was happy with the situation, because he expected Germany to win the war, and wanted to be on the winning side. The Jews meant nothing to him because they were not Roman Catholics.
