" that at least at the last stage of pregnancy, elective abortion is murder."

This is a straw man. 

Why do you think "elective abortion" occurs in the last stages of pregnancy when early abortion is legal (at least in the U.S)?  Do you think women just forget they are pregnant, or hope it will go away, or fail to notice the swelling uterus until 8 months have gone by and suddenly say, "Oops, I'm pregnant and I don't want to have a baby!"? 

No.  Women who wait that long WANT the baby and only abort when there is a very serious health issue or because something has gone terribly wrong with the pregnancy, maybe even, the fetus has already died in the womb.  This is tragedy, not murder.
