Angel's Mercy - Avacyn Restored

An angel of mercy or angel of death is a type of criminal offender who is usually employed as a medical practitioner or 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 encompass the healthy and the easily treated.
