Another act of horror and barbarism in the endless history of human beings slaughtering other human beings seen as less than human and not deserving of life. We will all mourn and wait in fear for the next horror while failing to accept our collective responsibility to prevent others and ourselves from becoming monsters when we demonize and dehumanize our fellow human beings! Who will lead us to act rationally and effectively to isolate and destroy the monsters around us while resisting the pressure to become hate filled monsters ourselves. What insights into history, sociology, psychology and humanistic philosophy might we employ to save us from ourselves?
