What Kind of Reversal Is This?

You're supposed to kill 'em, especially if they're crippled or ugly, not help 'em:

Researchers said Saturday they have used stem cells collected from the amniotic fluid surrounding fetal lambs to grow windpipes, and then implanted the tissue back into the fetuses while they were still in the womb -- a breakthrough that could lead to ways to repair congenital defects before birth.

Link.

I also object because the procedure apparently uses stem cells from a source other than aborted fetuses. There's obviously retroactive barbarism at work here.
