From my stand point, if it is certain that the baby is going to have a miserable life, be it either from poverty, bad habits or a bad parent, I would still want it to be a choice. I see that it can be classified as murder, but when you say it like that, it really pushes people away from abortion, even if in their given position abortion would be a better choice. I find it better to put a fetus to rest and not have it live through what it might, but this really just goes back to the euthanasia discussion, and I really dont want to invoke more bittering from there.
So from my view, abortion should remain legal, or maybe a choice given to families with situations that will make the baby´s life a living hell.
or you could be as straight forward as the gentlemen above me.
