Last year, an interviewer asked Francis how he envisages hell. His response stayed with me: “It’s difficult to imagine it. What I would say is not a dogma of faith, but my personal thought: I like to think hell is empty; I hope it is.”

I've always just assumed the descriptions that work to keep people fearful of leaving the religion as whatever is used at the time (saying this as somebody who is agnostic).
"Hell is a place of fire and torment" is explicitly Biblical (Luke 16), even if there are also mentions of Hell without that (and some mentions of fire and torment without calling it "Hell").
Annihilationism vs Eternal Conscious Torment is the main point that isn't given a perfectly clear answer in scripture; there are verses that hint toward each.
Limbo and Purgatory are not in the Bible, but predate Dante. "Deal with the Devil" predates Dante and is only weakly founded in scripture. "Devils" (plural, as opposed to "the Devil") being distinct from "Demons" is a translation artifact, popularized by Dungeons & Dragons. There being various types of demons long precedes Dante. Variants of Universalism (including "Nobody goes to Hell" and "it's possible to escape Hell") are explicitly rejected in scripture.
Those are all the aspects of "modern concept of hell" that I can think of (let me know if you can think of more), and the connection to Dante seems pretty weak.
