The more I think and read about psychopathy, the more I question as to whether it even exists.
The following is from a thesis on criminology.
"Psychopathy can be seen as the inverse of moral development. Some theoreticians (Shoemaker, 1990; Bartol and Bartol, 2011; Bernard, Snipes, and Gerould, 2011) imply that psychopathy constitutes a criminological theory. However, a clear mechanism or specific unit theory is rarely ever discussed, and it is debateable as to whether or not one actually exists."
