“Think about it – why would someone so desperately need to believe that there is no such thing as right or wrong, truth or falsehood, good or evil, personal responsibility, morality, the capacity for love and respect and courage and integrity? What possible motivation could there be for someone to burn from the universe all that glory and joy and possibility? How much horror must they have experienced – or inflicted – in order to call in an airstrike on everything that makes life worth living, everything that gives us meaning, everything that gives us responsibility and self-respect, pride and love, motivation and responsibility?”
