The Good Place is one of the best shows ever but in the end they basically just re-invent mortality. In the real world you die and we don't know what happens, in the fiction at the end of the show you die and then spend some time aligning yourself to the standard the main characters set, and when you eventually align with their morals for long enough you either stick around and atrophy until you're a forgetful idiot or you....die, and we don't know what happens.

The viewers of the show see bits of Eleanor falling to Earth and inspiring people but the characters do not know what happens.

If you want to get deeper, Michael the demon is granted mortality which means it can be done, it is shown as a special exception but over the course of infinite time either all demons will earn special exceptions and humans will eventually die and be unable to progress through the afterlife because there are no demons left to guide them through, or that doesn't happen in which case humanity will die out first and the demons will be left with nothing to do for eternity because all humans will eventually work through the system and disappear.
