Doing some research and wondering if anyone had something for me to look at. I'm currently researching the concept of a fallen angel that isn't "evil", one that is repentant or benevolent in nature or anything to that extent.
What are you classifying as a fallen angel? If you're referencing goetic demons, then non of them are inherently evil.
Angels and demons aren't what the Bible makes them out to be. Neither are evil or good. They're a mix of both, like any creature.
These are ones of good nature and enjoy human beings- King Paimon, Agares, Zaebos, Vassago, Orobas, Belial, Asmoday(Asmodeus), Belzebub, Lucifer, Amon, And even that crocodile god from Egyptian mythos which is almost a translation of Agares for whose name Im forgetting right now for some reason.
Theres a few more and probably thousands of unnamed ones that arent as known and documented that probably enjoy human beings.
King Paimon I can speak more of for that, as he enjoys observation, as much of a wonder that we consider these beings to be from our own perspective its comparable, and a mutual wonder of a different kind of living being.
