Lebensunwertes Leben, or "life unworthy of life". The phrase was applied to the mentally impaired and later to the "racially inferior," or "sexually deviant," as well as to "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. Later in the war, this policy grew into Hitler's "final solution", the complete extermination of the Jews.
