The fact that they were executed in a gruesome way should stop me from stating the obvious truth? Most of them DID go along with the war, as long as it was promising success.
What obvious "truth"? The only thing obvious about your statement is that it was made from the comfort of safety. Many of those executed had been against Hitler for a long time. You diminish the actions of people evidently far more courageous than you in your "easy chair".
