There is something I don’t understand about self defense.
Consider this situation: There are 10 doors in front of you, you know that 9 lead outside and 1 leads into a factory. You want to get outside, but are aware that you may end up in a factory (in which case you’ll go through the factory to get out). Well, you end up in the factory and find out that on the other side of the premises there is a man operating machinery that will kill you unless you find a way to stop him. This man is not malicious, he is doing what he does every ten years, you just got unlucky to end up in the factory at this time.
Well, suppose that the ONLY way to stop the man and save yourself from imminent death is to shoot the man.
Would it be morally permissible to defend yourself by shooting the man? It seems that it would be, but…
The answer should be no, because if a woman gets pregnant (having sex usually doesn’t lead to pregnancy, hence the 1/10 doors analogy), and then ends up in a situation where the pregnancy is life threatening (happens rarely, so the woman doesn’t expect it, just as the man in the factory doesn’t expect the guy to be there), she can do nothing that will directly harm the baby in order to save herself.
