No one here is vehemently opposed to protecting the unborn. We're talking about one specific case, of a very, very severely deformed unborn child, subject to the same oxygen deprivation that killed its mother, and therefore with very little chance of survival with any sort of brain function itself.
It was still a long time away from the point where it could even possibly, in a perfect world, if mother and baby were healthy, survive outside of its mother's body. And forgive me for the bluntness and the visual, but its mother's corpse was obviously decaying around it. The corpse was simply acting as an incubator for the hospital to pass oxygen and nutrients through, and I doubt very much that it would have remained intact long enough for the baby to be 'born'.
I'm sure the baby's father wanted his child to live, very badly. But there comes a time when it's nothing but cruelty to keep a such a horribly damaged being on artificial support, and everyone involved ultimately came to that realization. Once tests were done and the condition of the fetus became clear, even the hospital more or less admitted there was little chance for its survival.
