Depends? Morality like “don’t steal” is partially a consequence of game theory. Game theory is math.

Is math a social construct - obviously not.

The biggest fault of Game theory is that it is biased towards instant utility and short-term rewards. It does not model for scenarios where reduced short-term rewards can lead to greater gains in the long-term.

In short, decisions made for singular benefit typically have worse long-term results than decisions accounting for collective benefit.
