Medical training gave them the skills . . . Unfortunately evidence suggests that the medical profession is responsible for more serial killers then all other professions combined. Why is this so? Monsters of medicine chronicles the lives of five serial killer physicians in an effort to find a common thread in their lives. The author believes there is evidence to support that these doctors were all pathologic narcissists. Childhood abuse was present in all their lives. Medical training gave them the skills and opportunities for their murderous and torturous conduct. We are all patients and it is appalling to find institutions and monitoring bodies place reputation and potential liability above weeding out misconduct, incompetence, and our welfare. The fact that two of these killers were actively practicing medicine into the waning days of the 20th century should alert us that this subject is much more than just of historical interest. Key questions of cause, prevention, detection, and treatment are explored. Absolute answers are difficult to expose, but one thing remains almost certain. There is likely another serial killer physician practicing medicine at this time somewhere in the world.
