Morality doesn’t need to have anything to do with society or duty. Consider the case of an rational ethical egoist, to whom acting in one’s self-interest and for one’s own values is virtuous.
If that person is a human, and thinks that ethical egoism does not have anything to do with society or duty, then they are mistaken.
Maintaining interpersonal relationships is vital to the human condition. As Aristotle put it, “The solitary life is perhaps suitable for a god or a beast, but not for a man”. Friendships are a necessary part of flourishing for humans, and aside from that we are almost always in a context where our success depends upon our interactions with others.

Why?
Maintaining interpersonal relationships is vital to the human condition. As Aristotle put it, “The solitary life is perhaps suitable for a god or a beast, but not for a man”. Friendships are a necessary part of flourishing for humans, and aside from that we are almost always in a context where our success depends upon our interactions with others.
I’d guess because humans often contain concepts of duty and the like, and have experiences vastly contingent on social / societal contexts.
