Agreed. If you're stronger, you can kill the competition to increase your chance of survival and success- might makes right. This evolutionary principle was used to justify the greatest atrocities of the 20th century. A modest guess is 100 million people died because of the pseudo-scientific philosophy- mostly in countries during "peace-time."

Evolution, which clearly justifies genocide and other unspeakable horrors, is completely incompatible with Christianity which teaches that there's no reward for personal success here on earth. In fact "those who seek to gain their lives will loose them."
