I am LDS, is there a problem with that?

Are you playing devil's advocate

Well, in this case it is God's advocate. Apparently I'm advocating for Lucifer.

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.

You can fit, like, a gazillion of them on the head of a pin so they shouldn't even feel much in the way of tidal forces. Don't Angels have teleportation powers anyway?

Not in the LDS perspective. For us there are three (sort of five) types of angels. There are the spirits of people that haven't been born, the spirits of people that are dead but not resurrected, and the people that have been resurrected. The other are people sent from God that are not dead, being both those that are mortal and those that have been translated. The mortal one is uninteresting, one could probably find a grad student willing to do the experiment with the promise of a PHD. The others are the more interesting ones, being what effects does gravity have on spirit matter (being that for the LDS spirit is a type of matter) and what effects would it have on a resurrected body or a translated body. Destruction of the spirit is not a possible outcome. I have determined that, unfortunately, God is not likely to allow test subjects to volunteer themselves for the experiment and/or provide a convenient black hole for said experiment. Presumably once one is resurrected one will gain that knowledge.

Something like Teleportation, I am unclear on the details.
