In CR's case, he would have you agree with him that these are individual human lives being exploited in their earliest stage of a 'less worthy lifetime'; he would plead for a 'higher purpose' for these embryonic individuals, to sustain others who were not stripped of life support to harvest their body parts.
Then I gather CR wishes to stand in God's shoes. So to speak. So as to judge the merits of worthiness as between individuals, and to sacrifice the "lesser interest" to the "greater."
Geez. But isn't that the very formula used to justify totalitarianism, in all of its forms?
This is a completely specious line of reasoning, MHGinTN. CR is in absolutely no position to know whether the embryonic individual attains a "higher purpose" in its death than it would ever have in its life, had it been simply allowed to live. Unless one is to believe that the repair of a Hollywood actor's damaged body is a "higher purpose" than the live birth of, say, an Einstein, or a Mozart, or a Shakespeare....
