Wasn't he deeply religious and demanded that all Allied aviators captured by those under his command to treated civilly, and often would invite captured pilots to dine with him?
I remember reading about an "Experten" that always tried to aim for engine for his aerial kills, tried as much as he could to avoid hitting the pilot....can't remember who it was though.
That's the guy. He was still a General in the modern (then) West German Luftwaffe.
He was on a documentary a few years ago, visiting RAF and W.German jet fighter squadrons. A gentleman and all round nice guy.
