He will choose you, disarm you with his words, and control you with his presence. He will delight you with his wit and his plans. He will show you a good time, but you will always get the bill. He will smile and deceive you, and he will scare you with his eyes. And when he is through with you, and he will be through with you, he will desert you and take with him your innocence and your pride. You will be left much sadder but not a lot wiser, and for a long time you will wonder what happened and what you did wrong. And if another of his kind comes knocking at your door, will you open it? From an essay signed, "A psychopath in prison." Without Conscience: The Disturbing World of Psychopaths Among Us. -Dr. Hare

"The majority of psychopaths manage to ply their trade without murdering people. By focusing too much on the most brutal and newsworthy examples of their behavior, we run the risk of remaining blind to the larger picture: psychopaths who don't kill but who have a personal impact on our daily lives."
