"In the early 1800s, doctors who worked with mental patients began to notice that some of their patients who appeared outwardly normal had what they termed a 'moral depravity' or 'moral insanity,' in that they seemed to possess no sense of ethics or of the rights of other people. The term 'psychopath' was first applied to these people around 1900." Psychopaths are identified as people who lack emotion in psychological terms. They lack empathy based on emotions with their victims. Although they know how to speak, they lack understanding abilities, which is why they may mistake actions by others toward them as harsh. Not all psychopaths are episodic criminals. Some are just the kind of people society needs.
People with this disorder show a different behavior when they response or react to other people's actions. In my opinion, a lesson of morality could be learned from psychopaths. When you first look upon a psychopaths' face, they seem to be completely normal. They do not show weakness and most of them have high IQs, but their disorder is related to the severe moral insufficiency. What is wrong with these types of people? Why use violence to accomplish their goals? The answer is found in their minds. The part of the psychopaths' brain pertaining to emotions is damaged, which makes them very dangerous. A psychopath could watch a new born get thrown off of a bridge and it would bother them in any way. Another example is when I psychopath can lie with a straight face and act as if everything is okay. For instance, a father of a young sociopathic woman said, "I can't understand the girl, no matter how hard I try. "It's not that she seems bad or exactly that she means to do wrong. She can lie with the straightest face, and after she's found in the most outlandish lies she still seems perfectly easy in her own mind" (Cleckley, 1941, p. 47).
A psychopath has likes what he or she like, and dislikes what they don't.
