Frank Herbert said this quote
“ 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. ”
