"To me the choice seems difficult and clear: either we are committed to making a world in which all people are of value, everyone redeemable, or we surrender to the idea that some of us are truly better and more deserving of life than others, and once we open the door to that possibility, we cannot control it. If we are willing to say that some people don't matter, that some people are unaffordable for the planet, that some people's actions have placed them beyond the pale, then what forgiveness is there for any of us if we commit errors, even crimes? If we agree to accept limits on who is included in humanity, then we will become more and more like those we oppose."
