When you feel that you are inferior, when you compare yourself with others and see that they are superior to you, what will you do? The ego feels hurt -- you are inferior. You just cannot accept it, so you have to deceive yourself and others.
How do you deceive? There are two ways.
One way is to go mad -- you suddenly declare that you are superior, the most superior. Another way is to go politician. Either go mad or go politician. Through politics you cannot suddenly declare -- you have to prove that you really are the prime minister or the president. So it is the long way around. Madness is a shortcut to importance; politics is the long way. But they reach the same goal.
And if the world is to become a sane, normal world, then two types of persons have to be cured: madmen and politicians. Both are ill. One has gone the long route round, one has taken the shortcut. And remember well that the madman is less harmful than the politician, because he simply declares his superiority, he doesn't bother to prove it; the politician bothers to prove it -- and the proof is very costly.
What was Hitler trying to prove? That he was the most superior, the suprememost Aryan. It would have been better for the world if he had gone mad, used the shortcut; then there would have been no second world war.
Politicians are more dangerous because they are madmen with proofs. They are madmen working, reaching, achieving a goal, just to hide the inferiority in them. Whenever somebody feels inferior, he has to prove or simply hypnotize himself into believing that he is not inferior.
