Documentary Links Darwin and Hitler

WorldNetDaily has a story about an interesting documentary that contends Charles Darwin should share in the blame for the Jewish Holocaust:

Titled 'Darwin’s Deadly Legacy,' the stunning documentary shows that Darwinian theory, 'which is scientifically bankrupt, has probably been responsible for more bloodshed than anything else in the history of humanity,' Jerry Newcomb, one of the program's two co-producers, told WorldNetDaily.

Before the advent of Darwinian beliefs, said Newcombe, the Western world's basic concept was that man was made in the image of God, and was therefore valuable. But Darwin changed all that.

'Karl Marx wouldn’t embrace all (Darwin’s) tenets, but said, 'This is a scientific theory on which we can base our theory of man,'' Newcomb told WND.

Makes perfect sense. If we're all just soulless animals, what does it matter if you kill somone...or annihilate an ethnic group of people for that matter. If there's no eternal destiny for them, and no eternal accountability for the killer, how can we say its "wrong?"

Somebody explain that one to me logically, please.
