No. There is no "difficult moral conundrum" about torture, nor slavery, nor rape, nor genocide.

There are only people who inexplicably insist that a tortured non-sequitur is a pro-torture counterfactual.

That's one viewpoint. In some situations, it allows innocent people to die in large numbers. That's part of the moral situation too. Ignoring it, insisting it's all black-and-white, is easy from an armchair.
