If you look at the Nazi party, a major cult that destroyed Germany in 1945, Hitler could do no wrong in the eyes of his people, he called himself the father of the nation (fuhrer), He destroyed anyone that tried to oppose him in his party, he never listened to anyone around him who told him anything that was contrary to what he wanted to do, the German people stood by while their party slaughtered millions of Jews and minorities because the party could do no wrong in their eyes so they supported it down to the end when bombs were falling on Berlin.

This what a cult does. The only difference between Hitler though is that Hitler was an evil genious and Manning a dotish idiot.
