What were Hitler's and Mussolini's radical attitudes?

Another radical idea Hitler had was the genetic
engineering of a new Aryan race of white supremacy, and the physical destruction of
another.  He set up camps for Aryan pureblood SS members to breed (The "Lebensborn
Program")and encouraged them to have children out of wedlock, so that he could
eventually produce a master race, even as he was murdering millions of "undesirables" in
his concentration camps.

Mussolini's radical ideas included
totalitarianism, where the government controlled every aspect of the economy, society,
media and the state.  While this was his radical ideal, he never really achieved it, at
least to the degree they had in the Soviet Union.
