This is interesting from the Diagnostic and Statistical Manual of Mental Disorders.

According to the DSM 4-TR,"The essential feature of Antisocial Personality Disorder is a pervasive pattern of disregard for, and violation of, the rights of others that begins in childhood or early adolescence and continues into adulthood." (p. 701)

So here is a mental disorder that is, in fact, defined in terms of moral deviance. According to the DSM 4-TR, anyone fitting this diagnostic classification must satisfy the following diagnostic criteria:

3. impulsivity or failure to plan ahead
4. irritability and aggressiveness, as indicated by repeated physical fights or assaults
5. reckless disregard for safety of self or others
6. consistent irresponsibility, as indicated by repeated failure to sustain consistent work behavior or honor financial obligations
7. lack of remorse, as indicated by being indifferent to or rationalizing having hurt, mistreated, or stolen from another

B. The individual is at least 18 years old.

C. There is evidence of conduct disorder...with onset before age 15 years.

D. The occurrence of antisocial behavior is not exclusively during the course of Schizophrenia or Manic Episode (p. 706).
