Our existence is subordinate or imperfect in comparison to God's existence. If all that we see is inferior and flawed, evil and suffering should not be so alarming. Yes, it should still upset us, since that is no doubt part of its purpose. But it, as they say, "comes with the territory". If we acknowledge that our existence is imperfect and corrupted then we should come to expect horrific things to happen. We should also look forward with hope to a time when nothing is tainted and all is made new.
