An abortion is ending a pregnancy. A fetus can be dead, and the pregnancy will continue. Or the fetus can be unviable, and the pregnancy will continue. Almost always when talking about late term abortions (which you brought up) the fetus is at least unviable, and more often than not, actually dead. Which is to say that it cannot be murder.
The worst you could make it is desecrating a corpse. There are religions that would rather let a person die than desecrate a corpse, but I do not believe in that. Desecrate the corpse of a fetus all you want if it saves a woman's life.

If the baby is already dead, why the need to crush its head, Walter?
