1. Social pressures. Failing to care for others can result in social stigma, with increasing levels of alienation depending of culture/society;
2. Setting examples for reciprocity . One can help others today to set the expection to receive support later. All become old, sick and/or disabled at some point (if they don't die beforehand, immortals notwithstanding);
3. Friends and relatives are valuable in multiple ways;
4. Some just see value in helping others, either in the act or the results.
These are the examples I can state on top of my head. They all require each individual's evaluation scales to favor such motivations.
