Are you back again? When are you going to have your FR name changed...? It seems ill-suited to you in light of the above screed.
Forced sterilization in Germany was the forerunner of the systematic killing of the mentally ill and the handicapped. In October 1939, Hitler himself initiated a decree which empowered physicians to grant a "mercy death" to "patients considered incurable according to the best available human judgment of their state of health." The intent of the socalled "euthanasia" program, however, was not to relieve the suffering of the chronically ill. The Nazi regime used the term as a euphemism: its aim was to exterminate the mentally ill and the handicapped, thus "cleansing" the "Aryan" race of persons considered genetically defective and a financial burden to society.
The idea of killing the incurably ill was posed well before 1939. In the 1920s, debate on this issue centered on a book coauthored by Alfred Hoche, a noted psychiatrist, and Karl Binding, a prominent scholar of criminal law. They argued that economic savings justified the killing of "useless lives" ("idiots" and "congenitally crippled"). Economic deprivation during World War I provided the context for this idea. During the war, patients in asylums had ranked low on the list for rationing of food and medical supplies, and as a result, many died from starvation or disease. More generally, the war undermined the value attached to individual life and, combined with Germany's humiliating defeat, led many nationalists to consider ways to regenerate the nation as a whole at the expense of individual rights.
In 1935 Hitler stated privately that "in the event of war, [he] would take up the question of euthanasia and enforce it" because "such a problem would be more easily solved" during wartime. War would provide both a cover for killing and a pretext--hospital beds and medical personnel would be freed up for the war effort. The upheaval of war and the diminished value of human life during wartime would also, Hitler believed, mute expected opposition. To make the connection to the war explicit, Hitler's decree was backdated to September 1, 1939, the day Germany invaded Poland.
