Forgot a couple more of Rommel’s. He ripped up the “Commando Order”, and refused to implement it. He treated memebrs oof the Jewish Brigade, and Austrian and German members of the French Foreign Legion captured at Bir Hacheim as British prisoners of war [when they didn’t ‘wander off’], despite orders from Hitler to the contrary.
The conduct you ascribe to Rommel is not “standing up” to Hitler. Standing up to Hitler meant meeting him face to face and disagreeing with him. Rommel never did that.
What you describe was mere insubordination, even if properly motivated for humanitarian reasons.
