    Featuring a unique overview of the different forms of extreme violence, this book considers the psychology of extreme violence alongside a variety of contributing factors, such as brain abnormalities in homicide offenders. Featuring several contemporary real-world case studies, this book offers insight into the psychology of serial homicide offenders, mass shooters, school shooters and lone-actor terrorists.

    The main purpose of this book is not to glorify or condemn the actions of these individuals, but to attempt to explain the motivations and circumstances that inspire such acts of extreme violence. By adopting a detailed case study approach, it aims to increase our understanding of the specific motivations and psychological factors underlying extreme violence.

    Using nontechnical language, this book is the ideal companion for students, researchers, and forensic practitioners interested in the multidisciplinary nature of extreme violence. This book will also be of interest to students taking courses on homicide, mass shooting, school shooting, terrorism, forensic psychology and criminology and criminal justice.

    "The Psychology of Extreme Violence investigates the motivational drivers of those guilty of lone-actor terrorism, school shootings, and serial murder. Through a diverse set of case studies, their mobilisation toward violence is engagingly demonstrated. Collectively, it leaves us with a number of lessons learned for risk assessment and management purposes." —Paul Gill, Professor of Security and Crime Science, University College London, UK


    "Extreme killers are often analyzed in overly simplistic terms: either they were mentally ill, or they weren't. Fortunately, Allely brings a more nuanced approach by analyzing how neurological factors, mental disorders, psychological tendencies, environmental variables, and more can interact to produce serial killers, terrorists, and mass shooters. In applied case studies, she then demonstrates how the lives of perpetrators spiral out of control—before they take the lives of others."— Adam Lankford, University of Alabama, USA
