What you're trying to do is to strengthen your argument by arguing that the procedure is wrong because its immoral. I'm not gonna sit here and advocate for killing living things, but I don't pretend that its the only thing an abortion is, and then judge the situation based on that.
Abortion is simply an extraction of a fetus or an embryo, surgically or medically, whether its dead or alive, viable or non-viable. There's no alternate definition for it. Period.
