"Hitler was a wonderful actor. At times when he was beating his breast and assuring his visitor of his own devotion to peace, I was almost overwhelmed by the performance; and I was tempted to believe that my judgement must have gone to pieces in ever doubting the man's sincerity. But he was also so fundamentally wicked, and this appeared so clearly in his conversation that one's reason eventually got the upper hand. As the years passed, power visibly corrupted him. He became more intolerant of any opposition, more convinced of his mission and more openly ruthless. There was less need to dissemble and he almost gloried in his wickedness."
