I can think of a few more reasons beyond rescue.

- It's easier to find a significant other with whom to produce offspring if you exhibit kindness and charity to others.

- Generosity is often reciprocated.

- Giving implies EQ so altruistic person also likely takes care of family.

That's the issue with statistical models with finite decisions and states, they don't include enough parameters and interactions to capture anything relating to real life.

Like imagine a prehistoric human feeds a weak stranger, later that month the stranger warns them of danger. It's so obvious how kindness could be beneficial gene.
