You seem to have ignored the content of my comment. Your claim was that humans are not naturally disposed to charity or altruism...most of current anthropology disagrees with you. As inhabitants of a disturbed and unintegrated culture much of our natural evolutionary programming is overridden at an early age. This does NOT mean it doesn't exist or can't be a strong factor in human motivation, only that much of our current training and acculturation acts to counter and suppress it.
