Evil doesn't just naturally have the power to control, it usually requires a very charismatic person like Hitler to get the ball rolling then half truths and a convincing convenient lie like the country's misfortunes are down to a certain race or that men have oppressed women forever into slavery or that the environment can only be 'saved' if we sacrifice what we own....

Sometimes I think hermits are the most intelligent humans on Earth as they seem to know this and have peace'd out to middle of nowhere than deal with people being constantly convinced to hurt each other for a scapegoat mentality.
