Rudolf Hess, who ended up spending life in prison because the Soviets were upset he tried to end the war with England.
Hess was a German war hero in WW I and a German patriot.
Unfortunatly he also signed the Nuremberg Laws which eventually led to the incineration of millions of Jews.
I don't think that was his intent, but that was the outcome.
He was awarded the Iron Cross.
I think Hitler sent Hess on his mission. Hess worshipped Hitler and would have never done anything against Hitler’s wishes.
