Let me clarify that, shooting 7 year olds (or forcing puberty on five year olds so as to create babies before the parents are 8 and killing the parents before they turn eight so that it is a systematic sustained process (asking your sunday school teachers about such questions (or others like what happens if you pushed an angel into a black hole) can get strange reactions out of them, by the way, and make everyone else think you are crazy, but you already do so there isn't much to lose in sharing this)) only makes sense from an LDS perspective, unless you are already a psychopath. If you already were a psychopath then me sharing this won't change much. If you are not LDS or a psychopath then killing seven year olds should already be morally objectionable enough without further explanation

. If you are LDS killing seven year olds counts as shedding innocent blood which is an unpardonable sin. Further, not allowing agency was the plan of Lucifer and the reason he fell from heaven. Therefore, one would be implementing the devils plan by killing seven year olds as well as committing an unpardonable sin. Assuming that besides gaining a body the other part of the purpose of life is to be tested in all things then attempting to prevent testing is contrary to the will of God. Further, assuming that God knows what He is doing better then you do, being omniscience and all, then implement such a strategy would result in no net change to which persons will be saved in the end and which ones will not be saved and can only result in your own damnation.
