I finished the anime Death Note a few weeks ago, and it is probably one of the best of animes that I have watched. One of the things that always boggled me about the show was that any person who used the Death Note could never go to Heaven or Hell. Do they just sit around in limbo for eternity, or what?
Anyone who's watched the show to its completion will know that a million and a half people use the Death Note after episode 25. I just thought, "Wow, Light has just condemned all these people to hang around in limbo...For-ev-er". I think that nothing for all time is actually a lot worse punishment than going to hell, so therefore Light is a selfish bastard. But whatever, we knew that already.
I guessed that while the hundreds of characters that have used the Death Note are just floating around up there, they'd try to figure out everything that just happened in the show. I imagine it starting something like this:
Misa: "Did you really love me?"
Light: "...No."
