I am trying to get an idea of if whether he believed in God and Jesus, and what motivated him to do what he did..
"I believe today that I am acting in the sense of the Almighty Creator. By warding off the Jews I am fighting for the Lord's work."
~ Adolph Hitler, Speech, Reichstag, 1936"My feelings as a Christian points me to my Lord and Savior as a fighter. It points me to the man who once in loneliness, surrounded by a few followers, recognized these Jews for what they were and summoned men to fight against them and who, God's truth! was greatest not as a sufferer but as a fighter. In boundless love as a Christian and as a man I read through the passage which tells us how the Lord at last rose in His might and seized the scourge to drive out of the Temple the brood of vipers and adders. How terrific was his fight against the Jewish poison. Today, after two thousand years, with deepest emotion I recognize more profoundly than ever before the fact that it was for this that He had to shed his blood upon the Cross. As a Christian I have no duty to allow myself to be cheated, but I have the duty to be a fighter for truth and justice... And if there is anything which could demonstrate that we are acting rightly, it is the distress that daily grows. For as a Christian I have also a duty to my own people. And when I look on my people I see them work and work and toil and labor, and at the end of the week they have only for their wages wretchedness and misery. When I go out in the morning and see these men standing in their queues and look into their pinched faces, then I believe I would be no Christian, but a very devil, if I felt no pity for them, if I did not, as did our Lord two thousand years ago, turn against those by whom today this poor people are plundered and exposed."
~ Adolf Hitler, speech in Munich on April 12, 1922, countering a political opponent, Count Lerchenfeld, who opposed antisemitism on his personal Christian feelings."And the founder of Christianity made no secret indeed of his estimation of the Jewish people. When He found it necessary, He drove those enemies of the human race out of the Temple of God."
~ Adolph Hitler, Mein Kampf"The best characterization is provided by the product of this religious education, the Jew himself. His life is only of this world, and his spirit is inwardly as alien to true Christianity as his nature two thousand years previous was to the great founder of the new doctrine. Of course, the latter made no secret of his attitude toward the Jewish people, and when necessary he even took the whip to drive from the temple of the Lord this adversary of all humanity, who then as always saw in religion nothing but an instrument for his business existence. In return, Christ was nailed to the cross, while our present-day party Christians debase themselves to begging for Jewish votes at elections and later try to arrange political swindles with atheistic Jewish parties-- and this against their own nation."
~ Adolf Hitler, Mein Kampf"I am now as before a Catholic and will always remain so"
