With its mass murder of people with disabilities, the National Socialist regime crossed the line from racist and inhuman propaganda to the actual extermination of people they deemed unfit to live. These murders paved the way for the Holocaust, in that the regime made further use of the experience and “expertise” of central figures in the murder of people with disabilities. Methods used in their extermination were applied especially in the death camps of “Aktion Reinhardt” in 1943.
