no. abortion is without doubt termination of life. but i wouldn't call it murder if you were to terminate the life of a dog, a frog, a spider, a tree, one of my testicles (cancerous or not - there's a softball for you JL :icon_wink: ), etc..
You are welcome to use a term such as fetacide or something to describe an abortion if you want. I think its pointless to create a new word when it means the same thing as abortion, however. But since murder requires the willful killing of a person, it is very much different than abortion.
