The reality is Hitler and Darwin agreed on a whole when it came to race.
And Hitler and the vegetarians agreed on a whole when it came to diet and nutrition.
Does that make vegetarianism evil?
You have made the logical error of guilt by association, after having failed to distinguish that to the extent Nazis relied on Darwin for anything, it was an EXCUSE for their evil policies; not the impetus. If Darwinism were the impetus for evil Fascist policies, then, as has been pointed out to you already, every evolutionary biologist should turn into a mass murderer like Hilter did.
That they don't is proof that Evolutionary Theory doesn't CAUSE mass murder; that Hitler WAS a mass murderer is proof that something OTHER than Darwin made him do it.
