Just as long as the world doesn't end, Sam and Dean don't go to hell or get something else where they suffer forever, and any revived villains are re-killed or reform like Rowena and Ketch did. (Except Lilith or Azazel)

I really hope you're right and for the first time in a while I'm starting to think it's possible. Besides, I rewatched some Season 14 and realized that killing Michael voids all the other 14,000,604 bad endings. (roughly speaking, Infinity War reference)
