One of the most horrific terms in history was used by Nazi Germany to designate human beings whose lives were unimportant, or those who should be killed outright: Lebensunwertes Leben, or "life unworthy of life". First applied to the mentally impaired, later to the "racially inferior", or "sexually deviant", or merely "enemies of the state" both internal and external. From very early in the war, part of Nazi policy was to murder civilians en masse, especially targeting Jews -- which later in the war became Hitler's "final solution", the complete extermination of the Jews. Beginning with Einsatzgruppen death squads in the East, killing some 1,000,000 people in numerous massacres, later in concentration camps where prisoners were actively denied proper food and health care, and ending with the construction of extermination camps -- government facilities whose entire purpose was the systematic murder and disposal of massive numbers of people.
