Oh, Baby

“PLAYING God” is what medicine is for. Every Caesarean section and cancer treatment is an attempt to interfere with the natural course of events for the benefit of the patient. Not every procedure should be allowed, but a general sense of what is “unnatural” is a poor guide to what to ban. Transplants and transfusions were once considered unnatural, but now save many lives. That insight is why MPs were right to agree, on February 3rd, that Britain should become the first country to allow the creation of children with genetic material from three people instead of the usual two (see article).
By doing so, they hope to relieve terrible suffering. Faults with mitochondria—the tiny power sources inside cells—afflict about one child in 6,500, or 100 a year in Britain. The many conditions that result, a lot of them agonising and fatal, have no cure. So scientists hope to prevent them at conception, by transferring the healthy nucleus of an egg cell with damaged mitochondria into the body of an egg with functioning ones.
The procedure is not yet allowed anywhere else in the world, partly because it is new and untested in people but also because of the opposition that reproductive medicine often inspires. Mitochondria contain DNA, therefore any child born as a result of such intervention will inherit genes from three people—hence the headlines in Britain this week about “three-parent babies”. If the baby is a girl the genetic tweak in her mitochondria will be inherited by her children, and in turn by her granddaughters’ children. It is a “germ-line modification”, and thus irrevocable.
This ethical objection to mitochondrial donation is decisively outweighed by the good that ought to come from it. Mitochondrial disease is a misery to those who have it and a terror to those who fear they might pass it on to their children; curtailing it would be wonderful.

Is all life unequivocally important?

Is there any case where some life is more important than other life?
In the case of: Weeds/Food plants
In the case of: Murderers/Soldiers/Judges
In the case of: Unwanted Pregnancies/Women/Men


When can a person legitimately choose to prioritize some life over other life? Is 'legitimately' the most important operative in this case?
