No, the Holocaust wasn't the only bad thing Germany did. But very few of those bad things took place in Africa. You have to remember, Rommel wasn't exactly in the loop a lot of the time, and when he was, he routinely refused to believe what he was hearing. He was hardly alone in this. Many people had supported the rise of Hitler in the belief that all his outlandish statements were merely rhetoric to stir up the common people. There were even a few Jewish industrialists that supported him initially.
I don't know how Rommel could not be considered "in the loop" when he was supreme commander in North Africa and then in France. While Rommel held great admiration for Hitler until at least 1944, and believed in the nationalist part of Nazism, he was also consistent in his blatant disregard for orders to execute captured SAS, as well as orders regarding the treatment of Jews, both civilians and military personnel.
On the July 20 plot, a clarification: Rommel almost certainly knew about it, yet did nothing either way. He was, however, the only real choice as a non-Nazi successor to Hitler, regardless of the actual plans of the plotters. And he knew it. He also seemed to be actively planning to surrender France before his staff-car was bombed. This is little-known, as he never actually got to do it.
Rommel was most certainly a part of the July 20 plot. He and others were waiting for word that Hitler was dead before acting; the military governor of Paris acted to soon, as did Kluge, and both died for it. I wrote an alt-hist thread that began by citing parts of Rommel's writings, and it concerned this issue.
