““Typically, all it takes is a single life stressor to push one over the edge. It can be any devastating event, really—a car accident, job loss, bankruptcy, a terminal diagnosis, a child’s drowning . . . Stressors like those can create considerable challenges for a mentally healthy person. But when fate inflicts that kind of pressure on someone who’s already dangerously unbalanced . . . well, that’s how killers are born.””
