If one innocent person is tortured so that everyone else can live and the world doesn't end, is that simultaneously unfair but also morally preferable over complete destruction of everything?
This interpretation leaves out the most important part of the crucifixion story: Jesus willingly took on the world's sins out of love. So whether or not most Christians would say yes depends on if the one person being tortured has a choice in the matter, which is unspecified in the question.
