The vast majority of psychopaths, like an iceberg, are underwater, and like an iceberg, they are inert. They do nothing. They're just there. They torment their spouse by being unempathic, but they don't beat her or kill her. They bully coworkers, but they don't burn the office. They are not dramatic. They are pernicious. Most psychopaths are subtle. They are more like poison than a knife, and they are more like slow-working poison than cyanide.
