Honestly, it all comes down to what part of the military and the Nazi party they were. If they were just part of the Luftwaffe, the kriegsmarine or the Wehrmacht, you were probably just an average soldier.
However, if you were part of the SS-Totenkopfverbände, the SS-Sicherheitspolizei, the SS-Einsatzgruppen, or the SS Medical Corps (they gassed people, false title), you were probably absolute scum.
The oldest members of the party, whom had joined it before 1930, were called the "Alter Kämpfer", or "older fighter", tended to be the worst Anti-Semitics. They also tended to be the Amtsleiter, or those who personally answered to Adolf Hitler, and served as both his advisor as well as his body guards. I could go on, but not every German was "innocent".
After WWII, the American and Soviet governments ran a propaganda campaign called "Denazification", in which the guilt of the Holocaust was spread equally to the whole of the German people. German civilians and war veterans were often forced to view the work of their "Fuhrer" by touring concentration camps and working to bury the victims, and even in some cases to exhume mass graves.
