This is a fascinating response, and it's the sort of response I often get when asking a hypothetical question on any topic. It leaves me wondering if the person is unclear on the concept of hypothetical questions, or if he's pulling a James T. Kirk maneuver to avoid exposing some flaw in his reasoning.
Do any of you James T. Kirks want to try answering the hypothetical question again, this time without cheating?
If it makes it easier, I will stipulate that in the real world, people are notoriously bad at predicting the future. You could never have 99% certainty that some guy was going to kill you within a year. But in a hypothetical world where you COULD know that the odds were 99%, is it moral to kill that guy in order to probably save yourself?
