>Do the agents not ever question what they're doing morally?

Somewhat perhaps, but the victims are morally inferior to the agents, so the ends (career advancement for the morally superior agents) justify the means (unjust oppression of the inferior). It's a lot like when Islamist terrorists justify the killing of kafirs; but it's okay in this case because the injustice is committed by educated people wearing nice clothes, and for a good reason (justice!, or the children, maybe? or something else which I can't recall at the moment but I'm sure it's good for America).
