"Heydrich was informed about the smallest detail of Hitler's private life. He saw every diagnosis made by Hitler's doctors and knew of all his strange and abnormal pathological inclinations...They showed that Hitler was so ruled by the daemonic forces driving him that he ceased to have thoughts of normal cohabitation with a woman. The ecstasies of power in every form were sufficient for him."
