Kinda funny to me that the Decision sounds like this very deep and serious thing. People analysing it like deep philosophy about the world and all that. But if you think about it from God's POV, it's basically them asking for her to delete the Sims save file that went wrong and restart a new game (but this time "Please turn on "free will" in the setting and leave for coffee"), which is just the exact same thing God has been doing all this time already.
God: leaving Heaven unattended, come back to the angels waging wars on each other. Oh dammit better do damage control and separate the kids so they stop fighting.
God: Leaving Earth unattended and sometimes come back to see depraved things have happened. Oh that won't do. Let's tell the clearly unhinged and traumatized angels to deal with these regions somehow. (And the angels decided turning everyone into salt was a good idea lol)
God: Things got out of hand again, better flood 'em this time.
AziCrow's decision, how I see it, is just the same as what God has been doing. That's why She agreed to it so easily. The only difference that intriqued Her was the erasure of Heaven and Hell, and the evolutionary aspect of the new universe.
But they asked for it to be Godless!
No, She definitely did NOT erase Herself. God isn't stupid. And like every authority figure in the world, there is no way God would let these two characters have their wish. She has the ultimate power. why would She? There is no way the new universe is truly Godless. Maybe there's no Ineffable Plan, but it is not Godless.
No book of life, you say Well the Book of Life seems to be a record. It keep tracks of people and things related to life. It doesn't determine the future, but keep updating itself based on what is happening in reality. Changing the book is altering the past and not deciding the future is how I see it. Michael didn't write for the other Archangels to die. They had to burn the actual page to kill them. My point is, the BoL existing does not interfere with anyone's free will. It's just a tool to track down everyone and everything in the Good Omens universe from the way it's depicted. (Also a... teleportation device? Huh??)
Something is definitely out there. Their human versions just don't care enough to think about it.
As for whether it is meddling with the world or not? Well, if we take the ending with everyone present in the cafe, and Metatron/Derek still in Asa's life, as universe fact and not just because of filming budget and schedule, then yes. God is still meddling to get all of these people together.
She's still playing with her sims. Just in a different save file.
God's still playing her game.
Nobody won.
AziCrow actually lost, big time.
But AziCrow could have tricked her somehow!
1- It wasn't shown in the Movie. Nothing indicated they did this.
2- God is the most powerful being, with omniscience, in this universe. Being erased by her is not something you can come out of alive. She could delete them down to the smallest particle. They can't just turn very tiny to escape her.
But reincarnation!
1- Not a thing in Christianity for Angel/Demon to have souls. At least not to my knowledge.
2- Cannot have Reincarnation without a system to manage the souls. The logistic is not as simple as "they becomes souls and then reborn." It's more complicated than that. The concept of reincarnation, if you actually read about it in cultures that talk about it (not the whimsical, romanticised version of it), cannot exist in a universe without something/someone to keep everything in check. Things would fall into chaos.
See this post of mine for more thoughts on Reincarnation.
Bonus: This post about why Asanthony getting AziCrow memory back would be a horror story. Also some more aspect of reincarnation mentioned.
