Corruptions of Empire?

George Will continues his wandering off the reservation, in a column about Abu Ghraib:

That pornography is, almost inevitably, part of what empire looks like. It does not always look like that, and does not only look like that. But empire is always about domination. Domination for self-defense, perhaps. Domination for the good of the dominated, arguably. But domination.

And some people will be corrupted by dominating. That is why the leaders of empires must be watchful. Very watchful.
