The principle of sympathy for intense suffering (ed. that is, the alleviation of intense suffering has moral priority over everything else) defended here stems neither from depression nor resentment. Rather, as the name implies, it simply stems from a deep sympathy for intense suffering. It stems from a firm choice to side with the evaluations of those who are superlatively worst off. And while it is true that this principle has the implication that it would have been better if the world had never existed, I think the fault here is to be found in the world, not the principle.
