^^I don't believe in that commandment. I prefer "Thou shalt not kill." ;)
Yes, I do believe in the afterlife. And I am aware of your (DuracellEnergizer's) view on human life--quite existential if I remember correctly (can't remember where I read that, maybe earlier in this thread?). I'm equally curious as to your views on euthanasia, eugenics, murder, etc., considering "humans are the source of everything wrong with this world," or something along those lines.
As for how my religious views affect my perception of mortality and the value of human life, it could be a lengthy discussion better suited for my Mormon questions thread. To be brief and on topic here, I do not consider it justifiable to kill so children return to God, in spite of my belief that all children who die do indeed return to him. I believe there is more to it than that, and that God is ultimately the one who should determine when we leave this world.
