Yes, but Christianity is a fan-fiction of the Jewish bible. In the same way, the Quran is a fan-fiction of the former ones.
And the Jewish bible is full of fan-fictions of previous stories, like Gilgamesh.
A lot of Christians would object to that quite strenuously, and quite a few Muslims would stone you if you say these words in a wrong country.
That's why it's important to highlight the inconsistencies in the very logic of the religion.
Does it matter for what we're discussing?
I strongly disagree. Important towards what end? And if that end is getting people to be less religious, I think this is one of the least effective ways to make that point. Trying to dissuade a religious person in the basis of the logical inconsistencies in their religion is the le atheist approach, and seems to be most compelling to the agnostic and atheist crowds.

Mastema being yet another variation on embodiments of Yetzer hara, cause made real of the inclination of man to do evil.

Are you from Australia, or just a WWW fan of music from here?
When I was into The Expanse's Lang Belta (a creole), I was following BBC Pidgin: https://www.bbc.com/pidgin to get some feel for the possible antecedents. (UK:"Most read" = Pidgin:"De one we dem de read well well") Just to complicate things, what gets called "Hawai'ian Pidgin" is actually a creole as well, eg: https://www.youtube.com/watch?v=R15IQAVT7Rg (Is the use of "Aunty" parallel between this and Oz cultures?)
I'm just a fan. Thanks very much for the pointers into a new set of cultures* for me; up until now I've been enjoying cultural appropriations (consider the platypus!) in the other direction, eg polka acca dacca: https://www.youtube.com/watch?v=n_gtGfAail4 (and songlines I only discovered today while trying to figure out what the Oz equivalent of the https://en.wikipedia.org/wiki/Inuksuk might be)
* so far these mobs have been using a basketball court as an impromptu community centre/dance floor, which I guess they share even with very highly produced numbers, like "Baby One More Time"? As basketball had yet to be invented, earlier germans contented themselves with dancing around lime trees: https://de.wikipedia.org/wiki/Tanzlinde
Indigenous Hip Hop Projects have a youtube channel with community made videos from all over the country, eg: https://www.youtube.com/watch?v=GmKxmxk6Gas , https://www.youtube.com/watch?v=tFIOC078g6E - many in English | mixed, some in local languages. There are also channels such as https://www.youtube.com/@SkinnyfishTV/videos et al.
polka acca dacca covers songs by scots | brits adrift in the colony but the cultural appropriation doesn't stop there! (There are AccaDacca covers from across the globe) Yolŋu bands have covered AC|DC's Jailbreak https://www.youtube.com/watch?v=gaaxbNX-wg8 with a throw to aboriginal deaths in custody and another to the first indigenous language song that charted in AU: https://www.youtube.com/watch?v=ubxZsfyEwWY ..

Satan is initially described with his methods in Genesis, a Jewish work. Evil people often use the same ones today, esp in advertising and politics. Analysis of his methods below:
https://bible.org/seriespage/lesson-8-how-temptation-works-g...
Later, Satan is in Job and Zechariah 3. He's accusing people hoping that they get taken down. By Genesis, we don't need to know anything more about Satan other than to avoid or resist him. By Job and Zechariah, we know he's a consistent, mortal enemy of humanity across many generations. God's Word reveals more later but not much. Why not?
God's Word is about His relationship with and redemption of man through Jesus Christ. The books all combine into one story about how God saves us from ourselves for Himself by His grace and Christ's death. With that writing focus, he barely mentions most things in nature (eg angels). Same for most of the sciences. Why would God dig deep into a subordinate enemy in a book meant to glorify God?
The other angle is, once forgiven by Christ, God's Word is training for righteousness. We're to focus on loving and imitating Christ, and loving and serving each other. Much of what's in the Word supports those goals in different ways. Reading about lying angels that hate us wouldn't help at all. If we bump into them, invoking Jesus' name is all it takes to deal with them. He'll finish them off later.
Satan, as a figure was created (and described) by Christians. So it can't be anything but what it says on the tin.
It's not a real person whose biography they could have lied about - it's a creation they made of words, and those particular words define him.
You could reject their whole teachings and universe, but you can't really say "but what if Satan is actually good?", while accepting he exists. If he was good he just wouldn't be Satan. So it makes as little sense as asking "what if Moby Dick was really a rabbit?" - when Moby Dick only existed as a literary whale Melville conjured.
Similarly, as much as Satan is anything, and is useful for anything, it's for embodying the specific character he was described to be with the specific backstory.
You could write an alternate Satan (like the gnostic gospels do or Milton does), but that's fan-fiction then. The rabbit version of Moby Dick, not the "true" Moby Dick.
