AI, your opinion is not uncommon. However, ...
Depending on your religious beliefs and the way you were taught, it is valid to ask "what child" and still not be disingenuous. According to many religions, a fetus is not a child. Judaism and Islam share the belief that you don't have a child until the umbilicus has been severed. Technically, the Bible chimes in on this via the Solomonic decree, "The breath is the life" - meaning "first breath" as the starting point for life. There is NO passage in the Bible that claims that life beings at conception unless you start making exceptional readings of some passages where ordinary readings wouldn't say that. If a woman becomes pregnant and decides she wants to not deliver a baby later, and if her religion doesn't stop her, that is HER choice, not ours. If her religion or upbringing says it's not a child, then it is no different than having a tumor removed.
Given that many men are the "love 'em and leave 'em" type who use extreme persuasion on trusting young women, it is no surprise that a woman might wish to end any involvement with the cad who betrayed her trust. USA child support laws do their best, but I've know at least three or four young women who are now mothers but didn't want to be, and who were totally abandoned by their temporary partners. The bitterness that comes from such an event is something I would never want to inflict on a child. But society condemns that women for her unfortunate choice, leaving the "gunslinger" to roam around looking for more "notches for his gun." As long as society is still male-dominated, the "good old boy" network will perpetuate the need for abortion to be more freely available. And this doesn't even take into account those cases where drugs, actual force, or threats of force were employed.
Another point to consider:
Nowhere else do we kill children in response to the careless acts of the parent.
Not true. Abortions were known in ancient Egypt. We didn't get the idea here. We inherited it. World-wide, abortion is available with a few exceptions.

Many of the countries that allow abortion might place a limit on when it is possible by trimester, but only a few countries totally restrict abortion.
Let's also be clear that parents can condemn their child for being sick if they take extreme stances on medical treatments. For one example, the Church of Christ Scientist has many times gone on record as wanting to deny treatment on religious grounds. In effect, birth doesn't stop parents from allowing children to die - and in this case I'm using the word "children" precisely. Look at the religiously based "anti-vaxxer" groups that deny their children medically tested vaccines. And look at the recent measles outbreak in the USA northeaster sector that spread to multiple states because of a few kids in airports spreading the virus.
My wife and I agreed that if it were possible, we would have children, but it didn't happen. So I'm a step-dad and grandpa, but not a biological father. Doesn't matter, her kids respect me and come to me for advice, and the two grandkids love me. (It is a reciprocal agreement, by the way.) But we also agreed that it was always a matter of conscience.
