personal response to the evolution of goodness

I feel that it is highly unlikely that anyone should help another with absolutely no expectation of some form of return. A crude example is any job, when a worker works in anticipation of his pay. Some may argue of a counter-example, in which relatives help each other purely out of kinship. However, people who do good to their own relatives actually do expect something in return too. They expect to achieve inner peace by fulfilling their duty of helping their own relatives.

I come to the conclusion that there almost only exists “reciprocal altruism” in human beings; one helps another in expectation of requisition.
