Hah? By the end of the war Hitler was roundly reviled by most of Germany. If these conspirators were considered traitors for trying to assassinate the paper-hanging corporal it was by a decided minority.
It wasn’t only the conspirators - their families were also treated as traitors.
My father-in-law became a judge in Berlin after WWII and was able to restore von Stauffenberg’s widow’s pension for her husband’s service. It wasn’t popular.
