As to Marseilles; whether he could or should have shot down more bombers; or him being a glory hunter, well that's certainly possible. It's sure that he overclaimed, but that doesn't really make him stand out from the crowd. He did have the ability to manouvre his fighter into a position where he could shoot at and hit enemy aircraft, which was not a trait shared by most WWII fighter pilots. Any Hurricane or P-40 he shot down, was not coming back the next day to bomb or strafe Axis ground troops.
