dictator personalities
The trouble is, one kind of personality that makes a good dictator is also the kind of personality that doesn't give up power gracefully, or sometimes at all.
huh? Is there a dictatorship personality that gives up power gracefully? The only type I can think of is when it is given up directly to an heir. A dictator of any stripe would have to have an unusual amount of faith in a different form of government to simply bow out and walk away clean.
