To put another perspective on it: if you succeed and become Pantokrator, it won't matter what crimes you have committed, as Your will becomes the absolute law of reality, Your followers are exalted above all others, and those who have died in Your service are rewarded eternally (or at least until the wheel turns again). If you fail, it also doesn't matter what crimes you have committed, because you are cast into Tartarus one way or another and your former followers can only hope for mercy from their new absolute master.
That said, this game does have heroes in the traditional fantasy-narrative sense, so it's not all hopeless. Usually you meet them liberating parts of your empire or raiding your slave pens to free your sacrifices.
