Angel of mercy (criminology)

An angel of mercy or angel of death is a rare type of criminal offender (often a type of serial killer) who is usually employed as a caregiver and intentionally harms or kills people under their care. The angel of mercy is often in a position of power and may decide the victim would be better off if they no longer suffered from whatever severe illness is plaguing them. This person then uses their knowledge to kill the victim. In some cases, as time goes on, this behavior escalates to encapsulate the healthy and the easily treated.

The motivation for this type of criminal is variable, but generally falls into one or more types or patterns:

Some people with a pathological interest in the power of life and death tend to be attracted to medical professions or acquiring such a job. These kinds of killers are sometimes referred to as "angels of death" or angels of mercy. Medical professionals will kill their patients for money, for a sense of sadistic pleasure, for a belief that they are "easing" the patient’s pain, or simply "because they can." One such killer was nurse Jane Toppan, who admitted during her murder trial that she was sexually aroused by death. She would administer a drug mixture to patients she chose as her victims, lie in bed with them and hold them close to her body as they died. Another example is Harold Shipman, an English family doctor, who made it appear that his victims died of natural causes (disease). Between 1975 and 1998, he murdered at least 215 patients; he is suspected of having murdered 250 people. Dr. John Bodkin Adams, meanwhile, though acquitted in 1957 of the murder of one patient, is believed to have killed around 163 patients in Eastbourne, England.

An example of a sadistic medical serial killer was Richard Angelo, who was called the "angel of death", or angel of mercy. Angelo devised a plan where he would inject the patient with drugs, then rush into the room and attempt to "save" the patient so that he could be a hero to the patient’s family. This motive of excitement from inducing a health crisis for the patient has recently been labeled as a professional version of Münchausen syndrome by proxy, a type of factitious disorder. Richard Angelo confessed to killing 25 of his patients.
