Those who do not exist cannot suffer and are of no account to any viable ethics. If the true path to goodness is the elimination of suffering, then only those who must exist can be allowed to exist. It is the nature of life to favor existence over nonexistence, and to prefer the fertile soil to the poisoned wind. Because those who open their mouths to that wind pass from the world and leave no descendant, whether of flesh or of thought.
