Roby, I am curious....what makes you come to the conclusion that Hitler....or pick any other villain of history, must have been indwelt by a demon. We humans do evil, even great evil, with apparent ease.
In his youth, Hitler showed little ambition nor talent to do anything special. He fancied himself to be an artist, but his artwork was surpassed in quality by many 10-yr. olds. He eked out a living by making commercial posters for products, such as a brand of hand soap sold in Vienna. He tried to gain admission into a prestigious art school, but was turned down for lacka talent.
He obtained permission from the Austrian govt. to join the German army in WW1, and became a messenger, an essential but very-dangerous job before the development of radio. He won the Iron Cross, both first and second classes, for bravery. Yes, he REALLY won them; this was NOT propaganda trying to make him appear heroic.(He refused promotion several times, wishing to remain a "front-liner".)
It was during this time he found he had an ability to "speak" and sway an audience, when, in idle times in barracks, he expressed his views in the course of conversations with his comrades. After the war, he was employed by his old sergeant, Max Amann, as an "intelligence agent", whose job was to visit the meetings of the many small political parties and anti-govt. agencies that blossomed after the war. In between assignments, he began to practice his oratory on his barracks mates, even rehearsing in fronta a mirror. One of his assignments was to check out a small party called the German Workers' Party (DAP), and at its meeting, he became incensed at one of the speakers, and rose to deliver his own oratory. The whole roomful of people were mesmerized by his speech, and the rest is history!
While he had a few bumps in the road on his way to power, such as the "Beer Hall Putsch" which landed him in jail, his journey was mostly successful after that. Again, let us remember this was a man of average intelligence at the most, even though he was a voracious reader.
Hitler had dabbled in the occult in his youth, and that was probably the time the demon indwelt him. However, it didn't manifest itself in him until he joined the army, and then the demon only enhanced his speechmaking ability. It guided him into making all the right moves to obtain the Chancellorship. But once he became Chancellor, it led him to great success in everything...until France fell. Then, the demon left him, and, left on his own, he soon fell apart.
Given Hitler's history, it's highly-unlikely he coulda risen as high as he did, and stooped to such unprecedented evil as he did, especially in his fanatical hatred of the Jews, were he acting entirely on his own. And we see he went from master international manipulator and military leader to master idiot very swiftly, beginning with his allowing the British to escape at Dunkirk. But for awhile, he was still under some supernatural protection. He escaped one assassination attempt in which a normally very-reliable British time bomb was placed aboard his airplane, but failed to explode. This was the same type of bomb used to kill Reinhard Heydrich, and used by Stauffenburg in the "Wolf's Lair" assassination attempt. This mighta been an "acta God's", as He didn't want anyone to take credit for killing Hitler, or it mighta been an act of Satan's. We just don't know.
But, based upon the facts of Hitler's history, I believe he was indwelt by a demon, which manifested itself in him from his days in the army until the fall of France in WW2. This is, of course, merely my belief, with nothing "official" tied to it.
