Explain hitler's attitude towards the "handicapped."

On July 14, 1933, the Nazi government instituted the “Law for the Prevention of Progeny with Hereditary Diseases.” This law, one of the first steps taken by the Nazis toward their goal of creating an Aryan “master race,” called for the sterilization of all persons who suffered from diseases considered hereditary, such as mental illness, learning disabilities, physical deformity, epilepsy, blindness, deafness, and severe alcoholism. With the law’s passage the Third Reich also stepped up its propaganda against people with disabilities, regularly labeling them “life unworthy of life” or “useless eaters” and highlighting their burden upon society.
