Yeah, Rommel was rather a stickler when it came to proper treatment of prisoners. In one incident the Germans intercepted a British wireless order instructing commanders that prisoners were no longer to be allowed anything to eat or drink until after they had been interrogated (which might sometimes be a matter of days). Rommel interceded and sent a communique to the British arguing that not only was that a breach of the rules regarding prisoners of war, but it was the kind of senseless, petty act of cruelty that could only cause an already tragic (in his view) war to become even more bitter. The British, on reflection, agreed and withdrew the order. What I found most telling was Rommel revealing that his intelligence people had cracked the British wireless code. Churchill allowed Coventry to be leveled without evacuating the civilians in order to protect the secret that they had cracked Germany's codes, but Rommel threw away a similar secret in order to prevent mistreatment of his soldiers. (yeah, I know that the codes Churchill was protecting were far more important than the operational codes Rommel's people had cracked.)
