Women who seek an abortion usually do so because it is the pregnancy itself that is the problem. Whether for medical, emotional, financial or whatever reasons, they wish to end the pregnancy. That is what an abortion does, end the pregnancy. Yes, it does kill the developing foetus, but to call this murder is to misuse the term, which has a clear legal definition which does not apply to abortion. Whatever your moral views on abortion, it is not murder. If it really was murder, your post here implies that you are in favour of murdering people who are defective or " what not". I'm sure that isn't the case, but it does show that the foetus is not like other people, even in your eyes. Which one of the reasons why killing the foetus is not murder.
The pregnancy is not the problem. The problem is sexual immorality. If you don't like murder, we use baby killer instead.
A defective fetus (brain deformities, heart, internal organs etc) that can only survive for a few weeks or a few months is something illogical to give birth to it. The woman gives birth to it and then for a moment it dies just to escape being accused of murdering or killing it. It doesn't make sense. Why make the baby suffer when it's missing some parts? However, it makes a lot of sense of killing a perfectly normal healthy fetus.
It's not an excuse to kill the fetus just because of lack of money or something else problematic. Many poor mothers in poor countries give birth regardless of financial, emotional, etc. situation. They take care of a dozen kids without whining. While people in the wealthy west kill fetuses for convenience. A night of pleasure, the girl gets pregnant, and then aborts the developing fetus.
Using legalities to justify abortion doesn't make it moral. The law is not something that can be used to define what is moral and what it's not. It's only good for covering something that stinks using legal acrobatics. Killing a life is still killing it at the moment of conception. Life starts at conception and not when the baby is fully functional.
My stance is, give birth to it and then have it adopted. It's just a simple process of waiting. Hassle free. If the girl is already a day pregnant, she can advertise it to those who wants a baby. If there's a taker, then the couple takes care of the pregnant girl like a family.
