I don't buy your "pain as a condition for morality" thesis. Obviously I might be letting my feelings get in the way but consider this if that were true: We could have kept Terry Schiavo alive and harvested her organs, maybe or we could surreptitiously anesthetize people and eat their fingers. Hell we could live the life of vultures, feeding off the dead. India would never go hungry.
