Allowing the fetus to be dismembered and skull cavity collapsed? What else would you call it. Any woman who has that done to them, without legitimate medical reasons, should go further and be sterilized. Because they are too cold to be a mother ever.
Don't know where this came from, or what you are really concerned about. But to try to answer the question in your subject line, late term abortions must almost always be essentially heartless.
I'm an atheist, but the simplest medical technology allows me to see what is in the womb in the third trimester (and even the second). In my own opinion, you need a really, really good reason to terminate that. And I'm not sure many of the reason given are that good.
Look, bad things happen. Yeah, let your guard down a little and you might get pregnant. Maybe you have your own reasons why that is untenable. I don't like abortion, but I can't condemn a girl who, for her own, private reasons can't bring herself to carry a child to term. I don't like the idea of abortion as birth control -- that's stupid when we have so many better options. But **** happens.
But by the time that "accident" is developing a central nervous system, and feeling, then a decision to terminate becomes immensely more important.
I just wish we could all talk to each other more easily about sex. It's not that terrifying a subject!
