The mistakes (of leaders) are amplified by the numbers who follow them without question. Charismatic leaders tend to build up followings, power structures and these power structures tend to be taken over by people who are corruptible. I don't think that the old saw about 'power corrupts and absolute power corrupts absolutely' is accurate: I think power attracts the corruptible.
