I'm not sure if Hitler claimed to be Christian, but in any case he was not being a Christian when he was doing the things he is infamous for.
Just for the record, I’m not an atheist, but an extremely skeptical agnostic. If you didn’t know that, and observed my life, you would likely assume that I was a very devout Christian.
In that case you are closer to being a Christ-follower then those implementing the Spanish Inquisition. Being that the way you live your life is more in accordance with the teachings and examples of Christ. Those torturing the Jews may have been convinced they were following Christ, but I believe it when Jesus warned that there would be those that called Him "Lord, Lord" and yet be damned on the day of judgment when He will tell them "I never knew you". And there are many examples of Jesus being harsh on the religious hypocrites of His day. The term "brood of vipers" being used more then once.

I suggest you check out a couple sites site, of course blindly regurgitating atheistic dogma is far easier...Hitler used many words to accomplish his goals (ending pain and suffering through the irradiation of the “inferior” and “diseased” . so if Hitler said it it must be true?
no, but the starting premise of the existence of Morality to begin with depends on the Cause of Morality, (is morality more than a change over time, subjective opinion of mans mind? or are right and wrong independant of mans opinion of right and wrong?)
what is the Cause of Morality,
who is the Final Authotity on Morality? and why should we Listen to that Authority
Not entirely true, as their were Christians, Pagans, and atheists (Martin Heidegger being the prime example of the latter) who supported the Third Reich. Hitler himself occassionally attended Mass, but was more interested in the occult and Germanic mysticism more than anything else.
