Adam wouldn’t be in hell. It’s like the show forgot it’s own lore. The holy oil will kill the angel that tries to go through it. Cas threw a holy oil molotov. Micheal should have died. But say Chuck resurrected Mike. He would have done it like he did Cas. Rebuilt the body with no human soul.
Adam would be in heaven, people. I’m not sure why we haven’t grasped this as a fandom. We are better than this misunderstanding of our shows lore. We’re starting to get as bad as the writers. And that I cannot abide.
