FWIW, I would take the 1 in 3^^^^^3 chance of torture over a single dust speck*, but I would give 3^^^^^3 people a dust speck each than subject one person to torture, because the world with the dust specks looks nicer to me than the world with the torture. (I find fairness to be aesthetically pleasant.)

* Though since I feel like being pedantic, the - irrational - momentary anxiety of rolling the torture die would be a worse feeling than a dust speck, which in practice would make the dust speck the better choice.
