You would be surprised from how most of the things you are saying are, in one way or another, incorrect. I too believed these things once...
He did not want a war to begin with and was actively sending peace proposals after it started with the offering that all the borders remain as they were before the war, except for Danzig.
Hitler never wanted to be worshipped as some sort of God, he was a very humble person, his speeches do not exactly show what kind of person he is, but it just so happened that what he did for his people just got them to love him as much as they did, although other demagogues of his might have been trying to do that.
You say that he ruled through fear, yet you'd think that things like gun laws would be much more strict that would make it much harder for people to own weapons and this be able to resist, when, in fact, the complete opposite was done.
I cannot say much about him as a military leader, but, according to his bodyguard, Karl Wilhelm Krause, many times when the commanders that did not listen to him and did their own thing, battles were lost.
You can watch everything Karl W. Krause has to say about him, as he was one of the people that spent a lot of time in private with him and knew him very well. He also mentions some small to major events, like Kristallnacht, the outbreak of the war and so on, and what Hitler thought of them or had to do with them.

Other than that, why was he a great leader? Because he rose his people up from the ashes. From a dying and a demoralised nation he turned it into the most powerful one and gave hope, strength, will and happiness back to the people.
