Even so, I recognize that some authoritarian polities produce better lives for many of their subjects than some less authoritarian polities do. There's always room for improvement. A situation in which husbands don't beat wives because the people are educated in humane fashion is strictly superior, in my estimation, to one in which husbands don't beat wives because that would invite devastating punishment from the state. Even that latter situation is strictly superior to one in which husbands do beat wives and the state reserves its devastating punishments for other purposes.
However, that is not to say that the society blessed by humane education should make war on either of the other two, or on some society like our own in USA that is in some sense an average of all three. Humane culture is best spread by example, not by the sword.
