What exactly is the reasoning behind Satan ruling Hell? - No Stupid Questions - Fedia

Okay so Lucifer obviously upset his sky-daddy, is demoted from being an angel permanently, is cast down to rule an entire sector of the afterlife called Hell which we come to know where all damned souls go after they die....

It’s Christian fanfic. There is surprisingly little about Hell in actual scripture, definitely not the “hell” we’ve come to expect from modern media. Most depictions of hell originate from Dante’s Inferno, not from the bible.
Yup. As far as I’m aware most Christians would disagree with the notion that Satan rules hell, and it’s not a doctrine in any major denomination.

Doubt. Most Christians have never read the Bible, and their understanding comes from pop culture.
