The dark theory is that the supervillains are attracted by the superheroes, and that the whole mess would have never happened on such an overwhelming scale without the lure. It's difficult to think too seriously about the premise of super-humans, but if I try a bit, I have to reject the theory. I see it more like inventions happening simultaneously in different parts of the world. When the time is right for a concept to reach practical fruition, it does. The people who get the credit are just the lucky ones, the ones who happened to be there at the right time, and good fortune removed or prevented the obstacles out of their control. Similarly, if supers are going to happen, they're gonna happen. If the good ones do nothing, the evil ones triumph. And that's that.
