If we’re being truthful, Satan is supposed to be punished in hell too, its only modern works that portray him as the one ‘ruling’ and dishing it out to people in hell.

If we’re really being truthful, none of that stuff’s in the Bible.

Biblical Satan is a role, not a person. I’ve seen it translated as “opponent” or “rival”. Something like a “devil’s advocate” in catholic church - person or entity who tests somebody’s faith.

And Lucifer is again a completely different character, not related to Satan until much later.

The devils advocate in Catholicism is something very specific and not at all that. In order for someone to be determined a Saint there’s more or less a trial. One side presents arguments that say the individual has met the criteria by which one can be determined a Saint. The other side, which is called the devils advocate, attempts to poke holes in it and presents arguments by which the individual hasn’t met those conditions. They’ll do things like bring up sins and character flaws that persisted into the individual’s saintly period, as well as attempt to disprove any miracles the individual is said to have committed.
