Fb8f, please study a bit of biology. An embryo and a fetus are different concepts from a baby.
Also, the aim of an abortion is to terminate a pregnancy. Please try to understand this. If there was a way to terminate the pregnancy without negative consequences for the embryo/fetus, this is what people would do. Please do not assume that women who go for an abortion want harm for the embryo/fetus. Their decision is about their own body. What happens to the embryo or fetus is an unfortunate consequence.
Please look up the definition of murder. You will see that it is very different from an abortion in many regards. Let me just explain two differences here. In case of abortion, a non-viable fetus dies outside the uterus. Letting an organism die is very different from murder. First, murder requires killing, while abortion does not (letting something die is not the same as killing). Second, murder is about another person. When you look at those who are considered a person, you will notice that none of them have to live inside someone else's uterus in order to survive. So how can you call an organism that can only live in someone else's uterus a person? It seems that non-viable fetuses differ from persons in this important regard.
