Well, both the Church and the Pope did quite a lot actually, though arguably not as much as they should have done.
No, they didn't. For that they had been the leading power in the whole of Europe and could and should have done so much more to stop it. Hitler's whole anti-semitism and hence later the genocide on the Jews stemmed from his christian upbringing. To many followed him because of that christian tradition. Just google the images of Hitler shaking hands and smiling with the clergy.
Later many church leader supported the Nazis as it was seen as the lesser of two choices concerning the rising danger of communism. Better the Nazis than the Reds.
I would even go so far as to say the downfall of Christianity started in these dark times...
From that after-war-white washing:
"You know what happens when atheists take over-remember Nazi Germany?" Many Christians point to Nazism, alongside Stalinism, to illustrate the perils of atheism in power.[1]
to the truth:
...In contrast, Christianity had the capacity to stop Nazism before it came to power, and to reduce or moderate its practices afterwards, but repeatedly failed to do so because the principal churches were complicit with-indeed, in the pay of-the Nazis....
Its an eye opener:

Thats for you Lyzko:
...Attempting to deny that Nazi anti-Semitism had a Christian component, Christian apologists exaggerate the influence of Aryan neopaganism. Actually, neopaganism never had a large following.....
...especially not during the Thirties in Germany or elswhere in Europe, I might add. To make them now to a kind of main-perpetrators is truly ridiculous. As if a deeply christian country like Germany had become a hot bed of paganism over night or were not "deeply enough christianized".
All just tries to rewrite the true nasty history by the church!
