Several years after the first edition of Bad Boys, Bad Men was published, Donald W. Black, MD, brings us the Revised and Updated edition. Containing the same examination of antisocial personality disorder, Dr. Black continues to draw on case studies, scientific data, and current events to explore antisocial behavior in people. In this new edition, Dr. Black builds upon the succes of the previous volume and updates it with new research findings, including the genetic and biological determinants of antisocial personality disorder. Dr. Black also discusses the difference between, and overlap with, psychopathy. Several new cases have been added to Bad Boys, Bad Men including John Wayne Gacy, Mike Tyson, and Sadam Hussein. He also briefly discusses antisocial women, and provides a case example of Aileen Wuornos.
