Have you guys read books about him? At the end of the war, how Anthony Beevor described Hitler is very typical of an INFJ gone bonkers. He held on to the idealistic notion of a dramatic and heroic overturning of Allied advances and kept boasting about some "wunderwaffen" that never was. He saw betrayal and treason all around him and arbitrarily killed and fired able generals who disagreed with his "visions". He's the epitome of an idealistic visionary whose perfect world has no stake in reality. He banned any talk of defeat and surrender and was convinced of the infinite power of the Third Reich; he didn't know Soviet factories were out-producing German ones at an astounding rate, and infantry was outnumbered by a ratio of more than 10:1 and when a clever and perceptive officer put together these statistics, he insisted that they were fake. He believed a quality intrinsic in the Aryan race would allow them to overpower the Slavic soldiers. Sometimes, however, he privately admitted the imminent defeat.
He was stubbornly irrational despite having no experience in military strategy and insisted on some disastrous maneuvers for poetic reasons. For example, when it was wise to abandon (I think it was) Warsaw to concentrate their forces elsewhere, he couldn't bear the thought of giving up the capital city of an annexed land because it was symbolic of his victories and insisted that the troops fight to the death. Warsaw fell anyway, so did the other front. Towards the end of the Third Reich, he was increasingly paranoid (understandable, given the number of attempts on his life) and punished anyone whom he perceived to override his power in order to take emergency measures, even though conferring with him would cause a lag of a day or more, thus impeding swift military action.
