The good and effective dictator, that rules just and only has the well-beeing of his people in mind. Sounds good right? It might actually have existed a few times in history, but is the absolute exception. The reason for that is, that it includes an individual that has to have absurdly high moral standards and compassion in a system that encourages a totally different behaviour. Where should this moral come from? When somthing like that happens, it is not more than a fluke.
