You are on the balcony, taking some rest after studying for an exam when you notice out the window that there is a man standing beside the light post in front of the building. You will get terrified when you witness him killing a girl. You will get in a panic more when you see him deeply staring and snickering at you. It occurs to you that the man could be a serial killer just the like of the characters you watch in movies. Then, your hair will stand on end when you notice that he points his finger at the ground floor of the apartment building where you stay in. What do you think the man is doing with his finger? 
 Actually, this is a psychopath test, quite popular among my Korean students, to determine if you have what it takes to be like Jeffrey Dahmer. (laughs) Read your answer later. 
 In the past, to determine if one had the tendency to be a criminal was through the shapes of the skull. Cesare Lombroso, the founder of the Italian School of Positivist Criminology and considered as the father of scientific criminology, argued that criminality was inherited and that the "born criminal" could be identified by physical defects, which confirmed as criminal as" savage," or " atavistic". According to him, you were cut out to be one if you have the following traits: large jaws, forward projection of jaw, low sloping forehead, high cheekbones, flattened or upturned nose, handle-shaped ears, hawk-like noses or fleshy lips, hard shifty eyes, scanty beard or baldness, insensitivity to pain, and long arms relative to lower limbs. (http://www.newworldencyclopedia.org/e... theory is considered as a pseudo-science. In short, it has no scientific basis. 
 When American serial killer Jeffrey Dahmer made an earth-shattering headline across the globe in 1992, the people were flummoxed how they could know if someone they met on daily basis had the tendency to be like him. They could not get around the fact that someone quiet, reserved like him would be able to bestially kill more than 17 people, mostly Blacks, and preserve them in his own house in that no one in the neighborhood had had the idea of his heinous crime. So, many self-proclaimed experts from different scientific fields bombastically expressed their views ad nauseam until the people got cross-eyed to whose expertise they had to defer. Eventually, there is one thing they were in common- no one can guess whether a person is a psychopath or not because there are many behavioral patterns. However, Dahmer's behavioral patterns were unfairly used as the bases, particularly by parents, to preclude a child's psychopathic tendency. So, you have the tendency to be Jeffrey Dahmer if you did or do all of the following : 
 1.You made fun of animals by torturing them when you were still as young as in elementary because you were amazed at the internal organs of a living species. Besides, you wanted to collect their bones and skeletons. 
 2.You barely got along with anybody. 
 3.You started drinking scotch at early age. 
 4.You started to read porn magazines as well as porn videos at early age, so you jerked off many times in a day. 
 5.You always had financial problem. 
 6.You cannot express your sexual preference because of your conventionally filial atmosphere, so you are in the habit of frequenting at gay bars. 
 7.You fantasize people whom you want to sleep with. 
 8.You were a drop-out student. 
 9.You come from a broken family. 
 Although I was teeming with prejudice, I understood, with the help of my background in clinical psychology, that Jeffrey Dahmer was both a victim and suspect. He was a victim of what is so-called 'naked existence' as how Victor Frankl put it in his book Man's Search for Meaning, when his parents did not cater to him the atmospheric LOVE he wanted to feel and be exposed to. The divorce and conjugal misunderstanding between his parents also added to the fuel of his emptiness. In other words, Dahmer grew up in a world that he was ALONE, where no one guided and admonished him for his delinquent behaviors. Therefore, whatever the bad foundation built at his early age was the trunk of his life later on in that he became a serial killer. So, who should have been responsible for Dahmer's life? Himself or his significant others, particularly his parents? 
 I am not a true-crime votary, but I had interest in Dahmer's life story when my best friend kept on telling me about him. His name became immortal when I found out that American novelist Joyce Carol Oates wrote Zombie based on him. Fortunately, I found this biography 
 All I would say is that this book is perfect. First, the author is a known and trusted journalist who happened to be the first one to be tipped off when Dahmer's skeleton in the closet was found. Second, it is full of clear but blood-curdling accounts of how and why Dahmer became a serial killer- from the time he showed latent behavioral patterns to the time when he was killed. Finally, in all fairness, it knocked my socks off; I could not sleep at that night while reading it. I made sure that I heretically locked my door and windows as what I usually did when I was young whenever I watched crime stories. 
 The only thing that I cringed at is the author's nettlesome partiality for the policemen who were said to be incompetent in their job because they missed the fact that the man they were supposed to take over to the authority turned out to be Dahmer's victim. She argued that policemen were not perfect and had no any idea of what a serial killer's behavioral patterns are. Also, she reasoned that it was not easy to be in that line of duty since they stay up late to monitor around the city at nights. 
 These are the answers to the psychopath test above. You are normal if your answer is that he memorizes your face. You are a psychopath if you think that he counts what floor you live in.
