If the quickest (and perhaps ONLY) way to ban all other abortions (the 44 million you refer to) was to allow them for rape and incest (4 per year), what would you choose?
Of course, even though such a law would be wildly inconsistent. But in politics, you have to be pragmatic and take what you can get, even if what you get has absurd contradictions like this.
Latter. In the game Rainbow Six, counter operations always ended clean with no hostage caualties. In real life, a perfect operation is nothing short of a miracle. More often than not, many hostages died along the way.
Even if a few of these people can't be saved, there is no point in seeing all of them die. If that is the only choice, then I would ultimately choose the latter.
I have heard stories of rape victims bearing children and recall that many of them chose to keep them, not even putting them up for adoption.
Like I said, with much needed help, they would choose to do the right thing. And the only "casualty" will be the scumbag who defiled her.
