Manipulative phrasing. Of course, it will always seem worth torturing yourself, yadda yadda, when framed as a volitional sacrifice. Does your intuition equally answer yes when asked if it is worth killing somebody to do etc etc? Doubt it (and not a deontological phrasing issue)
Certainly there's a difference between what I said and the traditional phrasing of the dilemma; certainly the idea of sacrificing oneself versus another is a big one.
But the OP was asking for an instrumentalist reason to choose torture over dust specks. It is pretty far-fetched to imagine that literally torturing someone will actually accomplish... well, almost anything, unless they're a supervillain creating a contrived scenario in which you have to torture them.
When you will actually be trading quality of life for barely-tangible benefit on a large scal...
Admitting to being wrong isn't easy, but it's something we want to encourage.
So ... were you convinced by someone's arguments lately? Did you realize a heated disagreement was actually a misunderstanding? Here's the place to talk about it!
