There are many different Hells and many different Hell-Lords. Some death gods fall into that category as well, like Pluto and Hela, but not all.

I don't think Mephisto, and Hell in general, actually has much to do with the dead.

Good souls seem to go places depending on who they were. If Thor died he'd likely go to Valhalla.

Keep in mind that the underworld is not reserved only for bad people. Olympians will go to Pluto's underworld no matter if they were good or bad, and Asgardians will go to Hela's Hel unless they were remarkable enough to get into Valhalla.

The Fantastic Four did once go to a Heaven to find Ben Grimm.
