An embryo, by contrast, is full of potential and to end it is to snuff all of that potential out by a deliberate act of killing. The two are qualitatively different in both ethical and medical terms. One is entirely justifiable in moral terms, while the other is highly morally dubious.
You seem to think that I'm arguing from a position whereby all human life is innately sacrosanct. I'm explicitly not arguing that. I'm arguing that we should acknowledge first of all that we're ending a human life and then work from there.
