Malmquist recounts the psychodynamics of psychotic, borderline, dependent, narcissistic, masochistic, and depressed individuals. Embedded in these psychopathologies are the seeds for homicidal violence. Although he cautions that individual psychopathology alone is not a sufficient condition for homicidal violence, its interaction with other factors can progress to homicide. Psychotic, borderline, and narcissistic conditions have long been recognized as risk factors for violence, but Malmquist’s chapters on dependent, masochistic, and depressed individuals focus on conditions that are less often considered by clinicians to pose a homicidal violence risk. Malmquist describes an important example of how a psychotherapist’s misguided statement to a patient can be readily misconstrued as permission to kill. This book can serve as a useful guide for all psychotherapists to avoid such deadly errors.
