If a kingdom is ruled legitimately and fairly (enough) by a lich?

Err, while I agree that there is a place for black-and-white morality in fiction, you choose a pretty terrible exemple.

Warhammer is NOT a black-and-white morality setting. Some witch hunters are actually protecting the situations from threats, others are pretty much horrible people who commit horrific acts out of fanaticism or sadism.

That is because I did not use Warhammer as an example of black and white morality, but rather as an example of a setting that forces us to suspend our real world morality.
