Abortion is the killing of unborn children and it is morally defended on the ground that the unborn are not full persons. It is very important that you should understand that right up front. The killing is justified on the basis that the unborn are not full persons. The developing child therefore is described as a mere mass of protoplasm in a pre-human state. This ignores the fact that the developing child quickly assumes human form and that it can never become anything but a human being made in the image of God.
