All demons are grey in the dark by Dotfeather_144

Summary
"All cats are grey in the dark."
This is a proverb. It means in a figurative sense that someone who has too little information can't properly assess the situation. They can't distinguish between right and wrong.
When the Demon King died, the black line separating good and evil was broken. Having found new freedom, the demons take very different paths. Some relinquish their dark ways, some have their very own reasons to still follow them... But how can you tell them apart if you can't see in the darkness? How can you judge whether you're doing the right thing when all you can see is grey? And in the deepest darkness of misinformation, ignorance and crisis, only the cats seem to see through the night.
This story is a tragedy, just like Kimetsu no Yaiba. There is an ending. Is it a good one? A bad one? Is the dried cat blood on the ground worth it? Was it all worth it, were the dead, the lost, worth it, just so someone switches the light button on? Was it all worth it when you look around and realize that cat blood is just as crimson as a human's?

What if the hashira didn't fall into the infinity castle, and because of that all demons except Muzan survive?
