You may have heard of the recent surgery to remove a second head from a ten month old girl.
I found this very troubling for a couple of reasons.
1. The kept on refering to the "second head". Looking at the photograph and the fact that "it" could smile and blink, I would be inclined to refer to "it" as a conjoined twin.
2. By refering to the conjoined twin as a second head, it seemed as if they were trying to remove or ignore the personhood of the conjoined twin.
With all of that in mind, was it morally licit for them to have the twins seperated knowing that the not fully formed twin would surely die.
If the unintended consequence of the seperation is the guaranteed death of one of the children is it still permissable to have the seperation surgery.
First, I agree that the situation here is not merely a case of a "second head" but of a conjoined twin who happens to (a) be joined at the top of the head and (b) lacks a body below the neck.
VIEW THE CHILDREN (PRE-OPERATION) HERE.
(I won’t reproduce the photo here since it’s a little disturbing.)
The fact that the body-less child is able to blink and smile makes her personhood easier to demonstrate, but the fact that she is a head with a brain shows it as well. A head is not just an extra organ. If a child were born with an extra leg, you could remove the extra leg without it leading to the death of a person, but removing a head with a brain and not sustaining its life somehow results in the death of that person.
Consequently, it could be done only under those conditions in which it would be morally licit to disconnect on person from another knowing that this would lead to the death of the disconnected person.
Are there such conditions?
The closest well-thought-through situation is that of a mother with a tubal pregnancy. In such cases the child will definitely die when it grows too large for the fallopian tube to contain it and it will cause a hemmorage that threatens the mother’s life as well.
Catholic moralists have been debating about whether the law of double-effect may apply to the case of removing an ectopic child in the case of a tubal pregnancy. For a survey of the debate SEE HERE (scroll down). A consensus seems to have emerged that at least one type of surgical procedure (known as a salpingectomy) might be morally licit to deal with the situation.
One group of conservative moral theologians, including William May and William Smith, hold that the thing that makes a salpingectomy possible is that it is a procedure done on the mother rather than on the child. Specifically, the segment of the mother’s fallopian tube is cut out that happens to contain the child. The child will die as a result of this procedure (until such time as we can transplant the child to the womb or to an artificial womb), but the procedure does not directly kill the child (in contrast to other procedures, such as injecting methotrexate to stop the child’s placenta from developing and functioning. Since a salpingecotomy does not directly kill the child, it is argued to be potentially justifiable under the law of double effect (i.e., for a porportionate reason an action can be taken that is licit in itself though it will have a foreseen but unintended evil side effect).
If it were the case that the bodiless-twin was certain to die or posed a grave threat to the life of the bodied-twin (which would also result in the death of the bodiless-twin) then it might be possible to perform a procedure on the bodied-twin that would disconnect it from the bodiless-twin in such a way that the death of the bodiless-twin is an unintended but foreseen side effect, analogous to the case of a salpingectomy.
Unfortunately, the story give me no reason to think that the bodiless-twin poses any threat to the life of the bodied-twin. As far as I know, they could live a normal life while remaining conjoined. The bodied-twin’s heart might have to develop a little more to cover the extra blood pumping to the bodiless-twin, but no evidence is presented that this would be problematic.
Consequently, I have no reason to regard the severing of the bodiless-twin as anything other than murder.
