I recently read
Stuka Pilot by Hans Rudel. That man was a card carrying Nazi to the end in South America. I bet very few on any side in the war saw as much combat as he did, and boy did he. He describes meeting Hitler and Goering and his book is heavily sanitized. He saw a lot of combat and doubt he committed any personal crimes against humanity - his post war conduct did nothing to improve his image though. The Waffen-SS was a political organization that became militarized, it didn't have the professional background of the other German services. I don't know the background of the Waffen-SS Galicia Division specifically and anything with an SS label attached to it is highly suspect, but it doesn't automatically follow that this young man at the time personally committed any crimes against humanity. There were other French, Romanian, Ukrainian and if I'm not mistaken, Spanish SS units too. Not sure most care really, pretty sure I don't but I am pointing out that things are always shades of grey and rarely so black and white. Things got very mixed up at the end of the war.
There's a really good account of allied and German/Austrian units holed up in a castle actively cooperating to combat f SS units in retreat.
