That has nothing to do with morality. You don’t help people because it’s right. We help each other because we literally evolved to be social animals. Our biology in many ways depends on others. We feel individually sad and bad if we are isolated. And we feel good when we help others and see that people around us are doing well.
Morality has not been present throughout our evolutionary or even social history. Moralism only became an essential part of society after Christianity and other religions like it took over.
Things being “wrong” or “right” don’t help us really, materially. In fact, it’s mostly been used to control people and keep them in-line. After all, who decides what’s “moral”?
