There is a moral difference between a person who has “died,” and a person who has been murdered for their organs.
And my chosen parallel is exact. Skin is an organ, and embryonic stem cells are the pluripotent cells that, if not ghoulishly “harvested,” would have made up the organs of the child.
Indeed.
So by your reasoning, it would be okay to even use recent embryos that were being discarded. (Note that none are being destroyed expressly for the purpose of harvesting.)
