In Mein Kampf (I have not read the book myself as it is forbidden in the Netherlands) Hitler apparently accuses the Jews of having invented the conscience. By means of Christianity they then deviously managaed to infect the Germanic peoples with this affliction. This weakened the natural strength and will to power of the 'master race'. Hitler hated Jews, and he hated Christianity, because he held them both responsible for weakening the true, ruthless Germanic spirit. Hence his infatuation with the pre-Christian Germanic mythology.
