Experiencing Pleasure?

We would probably all agree that pleasure is experienced as good and pain is experienced as bad. And everyone would probably agree that arbitrarily inflicting pain on someone or some group of people is wrong.  Thus, a pain-filled life is not the kind of life that anyone would choose to live or think of as a good life.  Is pleasure then, and the absence of pain, the chief characteristic of a good life?  If they were, what would such a life look like? Would it be a life that seeks to minimize pain? Or, one that seeks to maximize pleasure? Would these make for a fulfilling life?
