It is certainly true that Hitler returned from the war as a man without a compass and embarked on a path of self-discovery. Yet opportunism and expediency and vague political idea coexisted and at times competed with each other, within Hitler.

By early 1943 Hitler had become perhaps the most isolated man inside the Third Reich, Every report was rewritten before it was given to him. He no longer saw the newspapers, though, to be sure, they contained little enough genuine information. He saw only clippings. The reason for all these precautionary measures was that nobody around Hitler fancied the hysterical outbreaks to which he was so addicted, and nobody wanted him to have any more brainstorms or intuitions of the kind which had already cost the army so dearly in Russia

After his arrest and internment in Munich, Hitler turned away from communism and ‘espoused the cause of Social Democracy against that of the Communists.’ He had to disown communism. If he hadn’t he would have likely been executed, imprisoned or banished from Germany.

Hitler: I'm not going to lie to you, it took a while. There were moments all along where I knew something was wrong. I remember one time... I think it was in Munich. We were having a rally. 100,000 people all chanting my name. The bonfires were going. The whole shebang. It should have been a crowning moment, but I clearly remember thinking, What am I doing here? I hate crowds.

In his view Herr Hitler had certain standards... Herr Hitler had a narrow mind and was violently prejudiced on certain subjects but he would not deliberately deceive a man whom he respected and with whom he had been in negotiation, and he was sure that Herr Hitler now felt some respect for him. When Herr Hitler announced that he meant to do something it was certain that he would do it.

Yet Hitler managed not to get caught up in the violence directed against real and imagined supporters of the Munich Soviet Republic. According to his friend Ernst Schmidt, he was released again from captivity through the intervention of an officer, who encountered him in the wake of his arrest and who knew him from the front.

Did he believe all that he said? The question is inapplicable to this sort of personality. Subjectively Adolf Hitler was, in my opinion, entirely sincere even in his self-contradictions. For his is a humorless mind that simply excludes the need for consistency that might distress more intellectual types. To an actor the truth is anything that lies in its effect: if it makes the right impression it is true.

[T]he German scene was transformed by the entry of Hitler: never before had a man so malignant attained such power, nor a nation shown so little revulsion from evil. Crude and hysterical, full of virulent hatreds and envy, he powerfully appealed to the Germans, and set about doing their work in Europe... Hitler had shrewd skill, but no wisdom; with him there was no appealing to reason or even to rational interests—which men like Chamberlain were slow to grasp. Nor was there in him a conscious control of his own moves; hence he appeared incalculable and chaotic.

Even Hitler didn't wake up going, "let me do the most evil thing I can do today." I think he woke up in the morning and using a twisted, backwards logic, he set out to do what he thought was "good." Stuff like that just needs reprogramming. … I wake up every day full of hope, positive that every day is going to be better than yesterday. And I'm looking to infect people with my positivity. I think I can start an epidemic.

After visiting these places, you can easily understand how that within a few years Hitler will emerge from the hatred that surrounds him now as one of the most significant figures who ever lived. He had boundless ambition for his country which rendered him a menace to the peace of the world, but he had a mystery about him in the way that he lived and in the manner of his death that will live and grow after him. He had in him the stuff of which legends are made.

Herr Hitler was possibly or even probably mad.

Hitler: Look, I was a bad guy. No question. I hate that Hitler. The yelling, the finger-pointing, I don't know... I was a very angry guy.
King: And this... new Hitler?
Hitler: I get up at seven, have half a melon, do the Jumble in the morning paper and then let the day take me where it will. Some days I'll fish, maybe hit the mall for an Orange Julius. The other day I spent seven hours in the park watching ants cart off part of a sandwich. Me!! The inventor of the Blitzkrieg... When you stop having to control everything, it's very freeing.

In 1918 Hitler was in a military hospital blinded from a British poison gas attack. He was just a corporal, he had no family, a limited education, no friends, no connections, no political status, nothing. He decides that he will lead Germany in redressing the grievous wrongs that had been done to it after the First World War and straightening out some of the mistakes that were being made in German society. And fifteen years later he is Chancellor of Germany and he did what he said he was going to do. A wounded war veteran with nobody to help him, and he pulled it up just through his own willpower. That is an amazing story. - The Fame of a Dead Man's Deeds, 2001

Hitler was undoubtedly a genius but he lacked self-control. He recognized no limits. Otherwise the thousand-year Reich would have lasted more than twelve years.
