Antisocial Personality Disorder (APD) is practically synonymous with criminal behavior. It's so synonymous, in fact, that practically all convicted criminals (65-75%) have it, with criminologists often referring to it as a "wastebasket" category. Psychologists consider it an adult version of juvenile conduct disorder. The main characteristic of it is a complete and utter disregard for the rights of others and the rules of society. They seldom show anxiety and don't feel guilt. There's really no effective treatment for them other than locking them up in a secure facility with such rigid rules that they cannot talk their way out. A full list of APD traits would include:
Sense of entitlement; Unremorseful; Apathetic to others; Unconscionable behavior; Blameful of others; Manipulative and conning; Affectively cold; Disparate understanding; Socially irresponsible; Disregardful of obligations; Nonconforming to norms; Irresponsible
whereas the DSM-IV "clinical" features of Antisocial Personality Disorder (with a person having at least three of these characteristics) are:
1. Failure to conform to social norms; 2. Deceitfulness, manipulativeness; 3. Impulsivity, failure to plan ahead; 4. Irritability, aggressiveness; 5. Reckless disregard for the safety of self or others; 6. Consistent irresponsibility; 7. Lack of remorse after having hurt, mistreated, or stolen from another person
Sociopathy is chiefly characterized by something wrong with the person's conscience. They either don't have one, it's full of holes like Swiss cheese, or they are somehow able to completely neutralize or negate any sense of conscience or future time perspective. Sociopaths only care about fulfilling their own needs and desires - selfishness and egocentricity to the extreme. Everything and everybody else is mentally twisted around in their minds as objects to be used in fulfilling their own needs and desires. They often believe they are doing something good for society, or at least nothing that bad. The term "sociopath" is frequently used by psychologists and sociologists alike in referring to persons whose unsocialized character is due primarily to parental failures (usually fatherlessness) rather than inherent features of temperament. However, this may only describe the "common sociopath", as there are at least four (4) different subtypes -- common, alienated, aggressive, and dyssocial.
Commons are characterized mostly by their lack of conscience; the alienated by their inability to love or be loved; aggressives by a consistent sadistic streak; and dyssocials by an ability to abide by gang rules, as long as those rules are the wrong rules. Some common sociopathic traits include:
Egocentricity; Callousness; Impulsivity; Conscience defect; Exaggerated sexuality; Excessive boasting; Risk taking; Inability to resist temptation; Antagonistic, deprecating attitude toward the opposite sex; Lack of interest in bonding with a mate http://www.angelfire.com/zine2/narcissism/antisocial_sociopath_psychopath.html
