I think you were clear. Maybe I wasn't. Those people who present themselves as not having a stake in the outcome, almost certainly do. They are the people who have withheld nutrition and hydration from someone (sometimes more than one person), or they plan to do that in the future. They usually don't reveal these motives, but sometimes they slip up. Don't think for one minute that they really believe torturing a person to death is the best thing for the victim. Nobody in their right mind really believes that. Anyone who wants you to believe it has some kind of motive. Usually it's to gain acceptance for an act they have committed, or hope to commit. It's rarely if ever because they really believe it themselves.
