Yeah, Lucifer is an interesting case. 99% of the Lucifer story is based on fictional writings rather than actual religious texts. Hence, I believe that how one views Lucifer (in writing and popular conception) is more of a Rorshach test.
I don't want to derail the thread, but it's a story which I have found interesting to study because of how many different ways it can be viewed.
To make some attempt at bringing it back to D&D, I find that 5E's version of the Gruumsh (Orc God) story is interesting in somewhat similar ways. Depending on how you look at it, he doesn't sound like the villain.
