That's a great question, and to anyone who has truly seen or experienced evil, any abstract conjecture would inevitably seem superficial posturing or ignorance.
That said, I will hazard an answer, and in this case it has to do with your question of "the world," and full disclosure, I approach the problem from an heterodox Christian POV. For in the cosmos, the created world, the everyday world of time and space that we inhabit, there is undoubtedly a great amount of evil. It's a question that is central to our existence here. This is the nature of the fallen world—thus the "natural economy" I refer to. But we distinguish between the things of Earth and the things of Heaven, the latter of which is the "super-natural economy" of Divine Love mentioned above, which generated the time and space so familiar to us...the one so filled with observable defect. The fact that we perceive such defect suggests that we on some deep level know that things ought to be otherwise—which is the fundamental Christian hope that, at the end of all ages, despite all the tremendous brutality and depravity in the cosmos, all things will ultimately be restored and recapitulated in the One—the will of Heaven made fully manifest on Earth.
Again, such an answer may be unsatisfying, especially when we regard the immediacy of the horrors around us. But it's the best I've got.
