For most people, the word “psychopath” associates with the hero of Alfred Hitchcock’s famous “Psycho” film. But in real life psychopaths can remain unnoticed in the crowd. You may have known a person for many years, but have no idea of the dark parts of his personality. True psychopaths rarely resort to physical violence, because they like more to play with people’s emotions. Often they use psychological tricks, such as domination and manipulation. Psychopaths know how to get what they need, so they like to play in such games.
