Well, I don’t really care which words are used, but I see it like this: In isolation, killing someone is a bad thing, as are stealing, lying and torture. So when you are choosing between otherwise identical courses of action, one which involves killing someone is worse than one that doesn’t involve killing someone. I suspect we’re all on board there…
Torture is also, in isolation, a bad thing. (Worse than killing? Debatable…) Therefore, when choosing between otherwise identical courses of action, one which involves torture is worse than one that doesn’t involve torture.
Of course, the rub comes when you have several possible courses of action, each of which have various likelihoods, to the best of your ability to estimate, of leading to various sets of bad things, and each of these courses of actions involves doing different numbers and types of in-isoliation-bad things yourself, etc., etc., etc.
Der Trihs makes the claim that torture is SO bad that no real-world situation would EVER result in a choice where the course of action involving torture is the ethically correct one to pick. That seems like an awfully extreme and overcertain statement to make, but it’s important to remember that I’m in agreement with DT that torture is awful, should be illegal, should be punished when it happens, made the US as a whole a worse place for its routine use, etc. etc. etc… we’re just disagreeing about likelihoods of fringe situations.
