Template:Beware the Superman
"[I]n any event, I never said 'The superman exists and he's American.' What I said was 'God exists and he's American.' If that statement starts to chill you after a couple of moments' consideration, then don't be alarmed. A feeling of intense and crushing religious terror at the concept indicates only that you are still sane."
—Prof. Milton Glass, "Dr. Manhattan: Super-Powers and the Superpowers," Watchmen
Superhero settings, like any other setting, end up somewhere on the Sliding Scale of Idealism Versus Cynicism. On the more idealistic end, you have settings like mainstream comic books, where there's a sense of wonder and basic decency about the superhuman. While there are villains, they will usually get caught or their plans will be thwarted, and while the setting may take dark turns, it will inevitably right itself. Somewhere in the middle, you have settings that look at superpowers a bit more realistically. While the government may have supers, so will despotic regimes, organized crimes, and terrorist groups. The good guys may win, but victories will be hard fought and likely to have their share of losses.
And then you have these settings. The world's not better for having superhumans. It's worse. The government has no safety net to deal with rogue supers, and it seems like there ain't nothing but rogue supers terrorizing Muggles or freaks on leashes. And that's just the so-called heroes, who are usually anything but, being all-too-aware of their superiority over the rest of the human race and a little too keen on arrogantly flaunting it. Maybe the crisis hasn't happened yet, but the way supers seem to be developing, it's only a matter of time until one of them blows up Pittsburgh and the rest go absolutely nuts. Not that they're exactly mentally-stable to begin with; many will gleefully screw the rules with their powers, but it's almost guaranteed that at least one of them is developing a God-complex as a result of their powers, and that they're only one bad day away from trying to enslave or wipe out all of humanity (which they could easily do within an afternoon).
