Dune was aimed at this whole idea of the infallible leader because my view of history says mistakes made by a leader (or made in a leader's name) are amplified by the numbers who follow without question. That's how 900 people wound up in Guyana drinking poison Kool-Aid. That's how the U. S. said "Yes, sir, Mister Charismatic John Kennedy!" and found itself embroiled in Vietnam. That's how Germany said "Sieg Heil!"
