I might help people because it makes me feel good, sure. But I might also do it because those are my values, long since established, and I try to live by said values. So it’s about what following a self-imposed expectation, not about getting something. For some people, some of the time.

Similarly, the argument that “being selfless is selfish” is not useful and provably false. Just go ask people, and they’ll tell you why they did things and how they felt. Then you have to argue that many of them are either lying or mistaken, which doesn’t seem like a winnable argument.
