Absolute power corrupts absolutely, if you will. By giving a sociopath, a psychopath, an enraged individual complete control over a nation — what happens? The overall destruction of man woman and child of those individual cultural boundaries. Your Hitlers, your Mussolinis, your Trumps. They manage to rally behind the darker areas of society’s fear and hatred. Now not only do you have a terrible, disastrous leader; you have a terrible and disastrous leader implementing racist and sexist and overall degrading values into a society that collapses under itself through hatred, fear, and war.
