The problem in that is that the evidence given was anecdotal, an example. It provides no evidence that Darwinism led to Nazism, nor that atheism did...it just shows the evils of a madman who was likely an atheist.

“We were convinced that the people need and require this faith. We have therefore undertaken the fight against the atheistic movement, and that not merely with a few theoretical declarations: we have stamped it out”. Adolf Hitler
“For their interests [the Church's] cannot fail to coincide with ours [the National Socialists] alike in our fight against the symptoms of degeneracy in the world of to-day, in our fight against a Bolshevist culture, against atheistic movement, against criminality, and in our struggle for a consciousness of a community in our national life”. Adolf Hitler
