One of the interesting aspects of the story is the way in which Hermann Goering went to so much trouble getting his brother out of trouble despite knowing in general what his brother was doing to help Jews to escape.
Yes, he did. It gives Hermann Goering's character a complexity that is a little disagreeable to moral absolutists but is rather intriguing. It excuses nothing, of course, but apparently yes, he knew what his little brother was doing, and covered for him.
