“They're dangerous people, and what's really frightening is that they don't know it, they don't see themselves as dangerous… they see the danger elsewhere. The danger is always elsewhere. How convenient.”

Dune Genesis (1980)
Context: Don't give over all of your critical faculties to people in power, no matter how admirable those people may appear to be. Beneath the hero's facade you will find a human being who makes human mistakes. Enormous problems arise when human mistakes are made on the grand scale available to a superhero. And sometimes you run into another problem.
It is demonstrable that power structures tend to attract people who want power for the sake of power and that a significant proportion of such people are imbalanced — in a word, insane. … Heroes are painful, superheroes are a catastrophe. The mistakes of superheroes involve too many of us in disaster.
It is the systems themselves that I see as dangerous.
