Is There a Difference Between Happiness and Existential Harm?

In cases of this kind, there's no significant difference between the badness of comparative and existential tongs. These cases count against the strong narrow personally affecting principles. Those who accept such principles often quote jan narviso's claim that though we ought to be in favour of making people happy, we need not bei or of making happy people. No such claim applies to existential harms. Compared with making people miserable, it would be just as bad to make miserable people. I shall now argue that when applied to some other cases, the narrow principles are structurally flawed and have soe other implications that are clearly false.
