Dualities are a very common image, and that's for a reason. Red and blue, hot and cold, strong and weak. They're easy to understand. The line is drawn in our head, a specter of a spectrum. In truth, perfect dualities are rare. Still, humans keep it in our minds that where there is evil, good will rise against it. Heaven is boring. Its members have figured this out by now, and they've learned to accept it. But when a story exists - whether an action movie, a sob story, a small-town hero, or a simple peace - conflict has to exist. A story without conflict can't really be a story at all, can it? How can we come to the bottom of the hill when there was no hill, just a nice walk through the plain? And so nothing cannot be allowed to exist. It either rises into something, or never exists in the first place. Sometimes, things happen from nobody's decision. Sometimes, the turmoil underground erects a mountain on the surface. Sometimes, good cannot be allowed to exist for the world to. And this time, the world will win.
