Some men break all the rules. They shirk everyday responsibilities, abuse drugs and alcohol, take up criminal careers, and lash out at family members. In some cases, they are nothing more than proverbial "bad boys." In the worst cases, their lack of a conscience allows them to commit heinous acts of murder, rape, and other violence. But what makes these bad boys become bad men who behave the way they do? This newly revised edition of Bad Boys, Bad Men builds upon psychiatrist and researcher Donald W. Black's groundbreaking work addressing antisocial personality disorder (ASPD)-sociopathy-in the 21 century. Drawing on scientific data, current events, new research, and real-world case studies-like that of John Wayne Gacy, O. J. Simpson, Robert Durst, Harvey Weinstein, Jeffrey Epstein, and even Donald Trump-Black explores sociopathic and psychopathic behavior in men and women whose cases read like detective stories. Far from being sensationalist. Black explores the history, genetics, and neurobiological roots of this misunderstood disorder that affects an estimated 10 million Americans. He takes on important questions such as: Which troubled children are likely to become dangerous adults? Can we be "born bad"? Can brain scans and genetic tests help diagnose ASPD? Can therapy help? What about medication? What can antisocial patients do to help themselves? Women are not immune from and behavior, and in this new edition Black discusses the woman antisocial, and takes up narcissistic personality disorder, which often intertwines with ASPD, creating an especially toxic combination of traits. Written to help patients and family members, Black explains that process of psychiatric assessment, diagnosis, and treatment planning. Bad Boys, Bade Men in essential reading for anyone interested in understanding antisocial and psychopathic behavior. Book jacket.
