Now we get to the really tough questions about abortion. Can we justify abortion in the really hard cases? Some might say that certain situations are so bad that even if we grant that the preborn are full human persons, we should still allow abortions to be legal, either for the sake of the woman or because it is assumed that a child would not want to grow up in one of these situations.
Each of these situations are powerful emotionally. These are very tragic situations in which we should really sympathize with the woman and/or the child in this situation. However, as I have previously shown, the preborn are full human beings. Therefore, the question we must ask is can we justify killing a human being in this situation?
A couple of things need to be said. From a philosophical point of view, these arguments all fail because they commit a very specific logical fallacy, the appeal to pity. An appeal to pity is made when someone tries to win support for an argument or idea by exploiting your feelings of pity or guilt. An appeal to pity does not address a legitimate argument made. Despite this, I don’t recommend shouting out “appeal to pity!” whenever you encounter someone who asks one of these questions. First, if you’re out on the street, it’s not really a formal debate setting. Second, the person bringing this up may be asking because of some painful event that occurred in their past or in the past of a loved one. Winning the person should always be more important to you than winning the argument (though of course, having a stronger argument is important), so we must use tact whenever we discuss these issues.
Additionally, if any of these hard cases justifies abortion, then we should note that abortion would only be justified in that case alone. None of these cases justifies abortion on demand being legal, which is what we currently have in the United States.  In this article I’ll respond to the case of fetal deformity. In a future article, I’ll respond to rape, incest and life of the mother cases.
If we were to justify abortion for cases of fetal deformity, that would only justify it for cases of fetal disability or deformity. So this argument does not justify the general right to abortion on demand.
Given that, this argument does not work to justify abortion. As I have written previously, the preborn from fertilization are living human organisms, even those who have some kind of deformity. So if we can’t justify killing a human outside of the womb due to having a handicap, then we can’t justify abortion for that reason, either. The issue is not whether the preborn entity in question is handicapped or how severe the handicap, but whether the preborn entity is fully human or not.
As Frank Beckwith writes, “…it is not clear that we can make sense of the notion that certain human beings are better off not existing…how can one compare non-existence with existence when they do not have anything in common? How can one be better off not existing if one is not there to appreciate the joy of such a ‘state’ (whatever that means)?”  Beckwith further notes that Former Surgeon General C. Everett Koop, who worked for years with severely deformed infants as a pediatric surgeon at Philadelphia’s Children’s Hospital, observed that “it has been my constant experience that disability and unhappiness do not necessarily go together.” 
The simple fact of the matter is we don’t know what constitutes happiness for others. We have no right to kill a preborn child because we assume that they would rather die than live with that deformity, even if we, ourselves, would rather die in that case (though it’s really impossible to accurately make that claim, not actually being in that situation). Indeed, as Randy Alcorn notes, doctors’ diagnoses are even sometimes wrong: “Many parents have aborted their babies because doctors told them that their children would be severely handicapped. Others I have met were told the same thing, but chose to let their babies live. These parents were then amazed to give birth to normal children.” 
Of course raising a handicapped child is difficult. They require special care and attention. But we cannot morally justify killing someone just because they are a burden. It is better to shoulder a burden rather than inflict evil.  If this moral precept were not true, then in our world the antidote would be worse than the poison, for people would have the right to harm another if it relieved them of a burden. All moral dilemmas could be solved by appealing to one’s own relief from suffering. 
But what about a preborn child with a very serious handicap, like anencephaly? According to the American Medical Association Encyclopedia of Medicine, anencephaly is the “absence at birth of the brain, cranial vault (top of the skull), and spinal cord. Most affected infants are stillborn or survive only a few hours.” It is important to remember that even in tragic cases like these, the preborn anencephalic human is still a fully integrated human organism, albeit a severely damaged one. Stephen Krason compares an anencephalic fetus to someone who has had their head blown off by a gunshot (a gruesome analogy but an apt one). This person is human and remains one until he dies.  As such, we are not morally justified in aborting this unfortunate child. The ethical thing to do is to allow nature to take its course.
As Edwin C. Hui notes, “In the event that such an unfortunate one is born alive, she is born a human person, and her short life as a person must be respected and treated with dignity as we would treat any irreversibly dying person. No heroic or futile treatments need to be provided, but neither should her organs be harvested for transplant. She dies and rests in peace as a person.” 
Christopher Kaczor would add that the expected lifespan of a human does not justify our killing them. We are not justified in killing death row inmates before their scheduled date of execution (be it for harvesting organs or other reasons). “The fact that a person at the end of life may have only a short time to live does not imply the permissibility of killing that person.” 
The solution to a serious medical problem is not to kill the patient, but to study the problem and come up with a solution. The problem should be eliminated, not the human (born or preborn) who suffers from it.
In my next article I will address the circumstances of rape and incest.
 Due to Roe v. Wade and its sister case Doe v. Bolton, abortion is legal during all nine months of pregnancy for essentially any reason.
