Humans are very good at killing each other. They’re also very good at justifying why they kill. I believe in order to kill a person, the human mind must firmly believe the other is exactly that–an other. The other is a stranger, different from you, and therefore inherently wrong because of their differences. The other’s existence is perceived as competition for resources that enable your “right” way of living. The other, therefore, becomes unworthy of resources, any semblance of mercy or even existence. This “reasoning” quickly snowballs into hatred, takes root in the soil of self-righteousness and grows tall and strong. Pretty soon the other is blamed for peripheral things, such as lack of work, a lack of prosperity or a lack of notice and regard that you clearly deserve. The act of killing is just a short step behind this hatred, patiently waiting to leap down from the rafters.
I think this is why the rabbi in the dusty sandals said murder begins in the heart. He knew; he told us. And yet we’re not listening. We’re killing, instead. Why? Because people who hate believe they are right to hate. And people don’t like to be told they’re wrong.
