Real talk..I question why people even believed Satan when he said he "ruled hell before the Golden Angel's fall" when Hazbin Hotel said how Hell came to be.

Dude was capping like a mother fucker + we already saw and knew before his debut that Lucifer was the Top Dog in hell,dude only doesn't rule cause he doesn't care.

Lucifer came first, this is basically a assistant CEO or a right hand being all like "I can say what I want now that the boss is out."
