A collection of lectures that examines violent and deviant conduct from psychological, social and legal perspectives, weaving together clinical observations, historical and case examples, and theoretical discussion to explore how societies define and respond to perversion and delinquency; it considers individual psychopathology, family and socioeconomic roots, and cultural influences, critiques institutional responses (medical, legal and educational), and advocates for nuanced, evidence-based approaches that balance public safety, accountability and possibilities for treatment or rehabilitation.
