Not so fast. Some virtue ethicists (especially Rosalind Hursthouse) explicitly acknowledge the possibility of what they call "tragic moral dilemmas," or situations in which no matter what you do, you act badly. Some examples of this involve situations that you get yourself into because of your own past bad actions (i.e. getting engaged to two different people, each of whom is ignorant of your engagement to the other). Another example might be something like Sophie's Choice, in which the titular character (spoilers, but I assume the statute of limitations here has passed) is asked by the Gestapo which of her two children is to be killed; if she fails to choose, both will be killed. According to Hursthouse, no choice you make in this situation constitutes acting well; you can disagree with her about this, but it would be a bit quick to conclude that her whole system is a failure because of how she approaches these dilemmas.
Yeah, I'm familiar with this sort of system, mostly via Thomas Nagel.
But I presume Hursthouse has a way to decide between different actions even if none of them can be described as acting well. The question of what to do doesn't just go away when you're in such a situation. I suppose one could punt and go with pure utilitarianism in those cases, though.
Or is this more a description thing? The morally superior choice shouldn't be automatically called "ethical," even if it is the right thing to do?
Whenever we get into something like this I'm reminded of General Buck Turgidson:
Now, the truth is not always a pleasant thing, but it is necessary now to make a choice, to choose between two admittedly regrettable, but nevertheless, distinguishable post-war environments: one where you got twenty million people killed, and the other where you got a hundred and fifty million people killed.
