I was watching girl interrupted lastnight and observing angelina jolie's character "Lisa". I realized that some of the people I surround myself around sort of have some of the characteristics she obtained. Sociopathy doesn't necessarily mean that your insane. So I did some research and this is what I found!
Antisocial Personality Disorder is also known as psychopathy or
sociopathy. Individuals with this disorder have little regard for the
feeling and welfare of others. As a clinical diagnosis it is usually
limited to those over age 18. It can be diagnosed in younger people
if the they commit isolated antisocial acts and do not show signs of
another mental disorder.
Antisocial Personality Disorder is chronic, beginning in adolescence
and continuing throughout adulthood. There are ten general
not learning from experience
no sense of responsibility
inability to form meaningful relationships
inability to control impulses
lack of moral sense
chronically antisocial behavior
no change in behavior after punishment
lack of guilt
If your friends have some of these symptoms most likely he/she is a sociopath.
