What? Pain has nothing to do with this. The positives outweigh the negatives by whatever criteria the giver uses to decide to do the act of giving. This is always true. No? Even self sacrifice, such as jumping in front of a bus, you deem to be the right thing - you chose an action because you believed it was a positive, for you, action. Just because you die doesn't mean you didn't still felt it was right, in that moment. If you do something you do not believe is a positive it changes from charity to masochism. You're doing it to punish yourself. If you're not punishing yourself, you're gaining something (or net neutral, i suppose, but that's difficult to define). edit: Though arguably even punishing yourself is self interest, as if you're punishing yourself it's because you want to.
