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.
