Darwinism = War?

I have seen this topic mentioned before and I am a bit curious as to what others think about it. My question is, how have Darwin’s theories, or other theories created off of his, contributed to inhumane acts such as war?Now, I feel that it is not Darwin or his initial theories that have any real connection to inhumane acts like war but I feel that theories taken and spawned from Darwin's initial theories may have gone toward such acts of violence. The whole concept of survival of the fittest has been taken to such extremes along with natural selection, Hitler and the extermination of the Jews seems to be a good example among many others.

So, what do you guys think?
