… First, it is never morally licit to choose
an intrinsic evil, such as abortion. The classic case is “Sophie’s choice,”
where the mother is asked to choose which child she will spare from death, or
both will be killed. The correct choice (though some ethicists disagree on this
point) is to refuse to choose even if both children will be killed, and even
if one could be saved, for if she chooses, she is cooperating in the evil.
“Sophie’s choice” should be differentiated from “the case of the runaway train.”
Here, you are driving a runaway train (that is, with no brakes) which reaches
a split in the tracks. On the one side is one person; on the other side are
two people. In this case, your responsibility is to choose the “lesser evil,”
which is the track with only one person. This case differs from the first in
that it does not involve cooperation with moral evil (you are not willing or
causing the driving force of the train), and that necessity therefore demands
a choice.
Both of the these types of cases, in turn, should be distinguished from “the
principle of double effect” in which, under certain circumstances, one must
choose a good even with the knowledge that an evil will result. The conditions
are: 1) the moral object must not be evil; 2) the evil result is tolerated,
not intended; 3) the good effect doesn’t result directly from the evil effect;
and 4) there must be a proportionate reason for doing the act. The classic case
here is ectopic pregnancy, in which the fallopian tube must be removed, even
when the result will be the death of the child. Here the moral object is to
save the life of the mother, and the action to achieve that object is removal
of the fallopian tube, not the direct killing of the unborn child. The death
of the child (a great material evil) is tolerated (not directly intended
or caused) because the moral object (the life of the mother) is sufficiently
proportionate to it. …
