The thing is, it entirely depends on how they are educated.
For example, if someone is told their entire life that they are an object to be traded away, they probably would never question it unless they saw someone just like them not being treated like an object.
This applies here, since if they always have been under this regime then they would know no different, and would not know that they are being oppressed.
Sure, one day it is bound to fall, but by that point your empire has probably fallen from other causes anyway.
(but i have the feeling this faction has been made specifically to be "super evil")
