Current Emperor: "The late emperor graciously established the non-aggression pact, recognizing your freedom."
Current: Emperor: "However, goodwill can be mistaken for a right!"
You're right about the latter, but you're quite mistaken about the former, the late emperor didn't establish the non-aggression pact out of goodwill for the benefit of the heavenly demon cult, he established the non-aggression pact so that they wouldn't exterminate the late emperor and everyone else in the empire who'd antagonize them, didn't you learn your history?
