You pose questions I have struggled with since I was a kid. Though I am not presently confessing a particular faith (I went from nominally Jewish to Episcopal, to lapsed when that church took a radical left turn), I had a naturally-occurring Manichean worldview as part of my childhood operating system. Early on, as I saw it, the world was divided into good and evil. I think the way good vs. evil can be taken into account (consistent with liberty and moral agency of each individual) is through a fair political process.
When it comes to abortion, the least bad thing we can do is legislate by majority rule in the states. My own belief is that abortion is always a moral wrong, evil if you wish. However, it is unworkable for a modern society to attempt to ban all moral wrongs. Early abortion falls into this category, as the individual rights of the woman exceed those rights which may attach to the zygote. This is especially so since the advent of reliable abortion-inducing substances which permit a woman (my view does not allow for the existence of pregnant men) to abort without involvement of any third parties like doctors or nurses - thereby removing this issue from “medical care”. As the important scientific realities exist on a continuum - and the state’s interest in the life of the fetus increases as the pregnancy progresses - I think the best compromise would be to ban all abortion through legislation after 15 weeks, for now. It may be restricted to earlier, should new knowledge of fetal brain function suggest it ought to be banned earlier.
In any case, thinking of abortion as mere “birth control” should be strongly discouraged. If we had anything resembling what used to be journalism, videos (which would be called ‘misinformation’) of ultrasound of the killing of embryos/fetuses - showing them obviously trying to escape the killing instrument (called a uterine curette) - should be made widely available. In this case, a picture would be worth very few words; what would follow would be gasps of horror and much silence. A less zealous defense of abortion would likely ensue, were actual knowledge of this reality of this barbarity to become widespread.
