While, of course, killing over 6 million people. Stalin is another example of this. "they have the interests of people in their hearts" is nonsense in cases like these. Stalin killed an estimated 34-50 million people. His own people. Interests of the people in their heart? Not so sure about this.

Like anything, it normally depends on the situation, but in typical terms, Monarchy trumps Dictatorships. In may cases, a Dictatorship form of government evolves into a totalitarian type, which strives to have complete control of the people-- Their thoughts, idea, religion. A Monarchy, which can evolve into a dictatorship, usually gives a fair amount of freedom (compared to the average dictatorship) to the people. Of course, there are exceptions for everything. For example, a Monarch, who may rule as a totalitarian ruler, may be thrown over by a dictator, and thus a reform. However, in usual situations, Monarchy is better than a Dictatorship.
