Full Idea
The doctrine of negative utilitarianism (that we should concern ourselves with the minimisation of suffering, rather than the maximisation of happiness) ...means we should support a tyrant who explodes the world, to prevent infinite future misery.
Gist of Idea
Negative utilitarianism implies that the world should be destroyed, to avoid future misery

A Reaction
That only seems to imply that the negative utilitarian rule needs supplementary rules. We are too fond of looking for one single moral rule that guides everything.
