motivated..by reason or by heart?

What drives us to show acts of kindness to another? Reasoning that stems from moral values that we ought to be nice? Or to win the company and support of friends in order to fulfill that human need in the Maslow's Hierarchy of needs - belonging? Or the knowledge that doing one good turn deserves another or put in a darker light, it allows for the use of that person in the future for one's own benefit?

or could kindness be driven from a natural, instinctive desire in us to help a fellow friend? is it borne out of the heart?

maybe the different factors contribute to our moral goodness. if one's acts of kindness is not shown out of love and this love is not given from God, then it can be said without a doubt, that one is not truly sincere and has a underlying agenda for that act of kindness.

since none of us can love perfectly, all our acts of kindness are tinted with sin, even if we consciously do it out of the goodness of our hearts.
