The main issue

How is it that Hitler became so vicious?
He was also a cute little kid when he was little.
Did he catch syphilis, was he possessed by an evil spirit, was he insane?
Does it matter, really?
Isn't the main issue why so many people began to worship him?
How do you explain that?

Did Jesus exist?

I have changed my mind. I nowadays believe that Jesus really existed, that he was not just a mythological figure. He was convinced that God very soon would overthrow the forces of evil and establish a new kingdom here on earth where there would be no more misery and injustice. These were the good news he was preaching. He was a Jewish apocalypticist. (“Truly I tell you, some of you standing here will not taste death before they see that the kingdom of God has come in power. Mark 9:1.”)

However, he was wrong. The evil forces crucified him and three hundred years later, they even began to use his name for their new religion. In 312, the Roman Emperor Constantine became a "Christian" after he had won a military victory. Ever since then have incredibly evil emperors, kings, dictators, presidents, warmongers and ordinary soldiers been professing Christians. And the Christian clergy have endorsed them and prayed for them. The evil forces have rejoiced in nearly two thousand years now.
