[Marvel/DC] What would the two universes look like if characters who have died STAYED dead?

In superhero comics, it's an infamous joke that everyone who dies eventually gets brought back to life, except for Uncle Ben and Bruce Wayne's parents. What would Marvel and DC look like nowadays if the characters who died really remained dead? Just to throw a few names out there, I know that Hal Jordan died in the 90s, Superman was infamously killed by Doomsday, Batman's sidekick Jason Todd was bludgeoned to death by The Joker, Barry Allen died during Crisis On Infinite Earths, etc. By the way, I'm only counting deaths that took place in the current main continuity, not deaths that occurred in alternate universes.

In the Infinity Gauntlet crossover, Thanos literally kills half the Marvel universe. Japan and the US West Coast are completely destroyed. Casualties include Spider-Man, Iron Man, Thor, Captain America, several cosmic heroes, Vision, and several X-Men.

If none of them can be brought back as they were in the story, it seems likely that Marvel will devolve into a villain-ruled war zone in the early 1990s, as there will be much less power to stop the biggest villains from expanding their territory until they crash into one another.
