i think that everything you do that is not instinct/reflex is a self willed action. you do it something or don't do something because you want to or don't want to. "i don't want to get hurt" (self willed- avoid pain) "i want to help that person" (self willed- gain pleasure) unless you decide something before you have time to think about it (instinct/reflex), then its self willed in my opinion. you always do what is in your best interest, if you know doing helping someone is in their best interest... all you really want to do is help that person. you have to ask yourself why. why? why do i WANT to help this person? because it makes you feeeeel gooooood. =D
Probably the most right answer. It might be that we are hard wired to feel good to help others. Sounds like a strong case can be made that it gave us many evolutionary advantages and is why we see it in a large part of our population.

What prompts a human being to act heroically? What makes us perform good deeds? When we act on behalf of other people, research shows that
they feel greater comfort, less stress. But what about the do-gooder's physiology how is it affected? Can doing good make us healthier, as a growing number of scientists now believe? Can it even, as studies suggest, help us live longer?
This is the focus of 50 scientific studies funded through The Institute for Research on Unlimited Love, headed by Stephen G. Post, PhD, a professor of bioethics at Case Western Reserve University School of Medicine. It is a comprehensive investigation of altruism, aka benevolence, compassion, generosity, and kindness.
