Hitler wasn't an Atheist.
He was a corrupt Christian.
The KKK, and other cruel acts happened among churches.
The slaughtering of Native Americans, the kidnapping of Africans, the wars were
all supported by so-called Christians.
Hitler was a terrible and hateful man.
Anybody can develop into a Hitler if they give into such tendencies.
Pride, Anger, Hatred, Violence, and Selfishness.
Even Angels in the Past sinned. That's why they are now demons.
Satan at first was an angel, but because of the rebellious attitude and selfish thinking consumed him, and he became the Devil.
Anyone can turn into Evil. That's why we need to guard our heart and not follow it.
"The heart is more treacherous than anything else and is desperate."Jeremiah 17:9.
We need to read and study the Bible daily, and pray to Jehovah God for guidance and strength from such temptations.
We are to seek peace and pursue it.
