I have no problem with pain and suffering which is volitional. If someone wishes to emulate Jesus’s passion by having himself crucified, that is his own business, and no one should interfere.
We could not p(name removed by moderator)oint it with 10 decimal’s worth of accuracy, but we sure can make a good, educated guess. Suppose that someone could point out the greater good, which was the direct, logical corollary of the holocaust. It would be clear that if the holocaust never happened, then this “good” would never have come to pass. So at that point we have some untold amount of suffering, which was logically necessary for the ensuing greater good. So far, so “good”.
This is the question: “suppose that one of the victims would have avoided the capture, by sheer luck” (there were many who did). To make the holocaust “logically necessary” the proponent of the “greater good defense” in under the obligation to explain why and how the lucky escape of one person would have negated the “good”.
