Heinrich Himmlers Warning

In May 1940 Himmler wrote: “we reject the Bolshevist method of physical destruction of a people as un-Germanic and impossible…”
The German SS arrested Buchenwald Commandant, Karl Koch in 1943 for mistreating and even executing some prisoners. After an investigation Koch was found guilty by SS Judge Konrad Morgen and shot. Does this sound like a policy of “extermination?”
