Most people assumed that it would be the opposite--that the victim of such horrific violence would naturally be repulsed by any future bloodshed. But the truth was, the world does not work that way. Violence breeds violence--but not just in the obvious, retaliatory way. The molested child grows up to become the adult molester. The son traumatized by his father abusing his mother is far more likely to one day beat his own wife. Why? Why do we humans never really learn the lessons we are supposed to? What is in our makeup, in fact, that draws us to that which should sicken us?
