Most humans are both good (empathy is a strong thing) and greedy (wanting what's best for yourself and those are you close to is also a strong incentive). Balancing those two, sometimes opposing, desires is part of being human. It's worth noting that they're not always opposing. Sometimes empathy makes us feel better when others feel good, and the negative impact on ourselves can be more than countered by the good feeling from making others happier.
