The above sentence is the best evaluation of him.
He is well-read, elegant, proficient in six languages, and can fly a plane, and quickly captured a large group of believers with his unprecedented evil talent. But he doesn't smoke, drink or like women. It seems that the sage-like life attracts everyone like fans, and admirers come in droves.
When Hitler stepped onto the stage of the supreme rule of the German Empire, it was doomed that he would be a unique leader, firm and wise.
Decisive and keen, the devil incarnated him perfectly. Using his own skills, he violently and forcefully eliminated opponents within the party and thoroughly implemented a set of reform programs. Most importantly, his reform hardly infringed on the interests of any class in Germany (except Jews), but almost everyone benefited from him. The political wisdom revealed in the reform is like the devil's eyes, so appropriate and in place. If the implementer is not a demon, then this reform will definitely be the best reform in history.
