In superhero comics the world is identical to our own aside from horrific collateral damage being wreaked every week. Super villains regularly destroy cities and murder millions. The mundane crime rate is unsustainable orders of magnitude higher than in the real world.
Clearly something is maintaining the status quo so that civilization doesn't collapse. The ashes of cities are raised up good as new; the mountains of corpses are resurrected and sent back to their jobs. Life goes on as usual. Another day, another world ending disaster.
Why would that world even remotely resemble our own? If people are living in Purgatory, why aren't they acting like it? Why do civilians keep going about their daily lives? Why do criminals keep committing crimes if everything resets?
