And remember - you had to sign up to be a Nazi. Most Germans weren't. Nazi membership wasn't compulsory. In fact, if you were a higher up in the military, you COULDN'T be a member of the Nazi party (although more than a few Wermacht generals were Nazis in Spirit if not in name). To be an SS member, especially a Camp Guard, meant that this individual would have had to have been a volunteer, an enthusiastic Nazi party supporter. Again, they didn't give camp jobs to anyone - they made SURE that only the most sadistic, racist, brutal members of the SS got that job.
I really have no sympathies with any Nazi Party Member above the age of 18. I will grudgingly accept that maybe some of the Nazi Party Youth members should be spared (since a lot of them were pressured into it by their parents), but anyone who joined the Nazi party as an adult doesn't deserve sympathy. Again, a lot of Germans weren't Nazi Party members. Most Germans, in fact, weren't Nazi Party Members. He had a choice, and it was not a "Life or Death" Choice - it was a choice between Career Advancement and Wealth, or morality. To join the Nazi party incurred great privileges and opportunity. To not join the Nazi party would lock you out of the highest jobs, but you could still have a pretty successful career. To those who joined the Nazi Party - either they must have been racists who agreed with what the Nazi Party espoused, or they must have cared more about getting that next job promotion over the rights of their fellow citizens. Again - joining was purely a choice. If you didn't want to join, you didn't have to.
Not all Nazi party members were guilty of war crimes, but odds are if you worked or had anything to do with those camps, you ARE guilty of war crimes. SS members were almost certainly, to a man, guilty of crimes against humanity. During the war with the Soviet Union, you had entire SS divisions following behind the regular army, and their job (which they did efficiently) was to just kill all Jews and anyone suspected of being members of the Communist Party, as well as to "punish" villagers for partisan activity. They would machine gun hundreds of people from a village just because a German soldier was killed by a partisan near-by. They killed and starved, ON PURPOSE, at the very least hundreds of THOUSANDS of Russian citizens who had done no harm to them.
Given the SHEER AMOUNT of blood shed by the SS (and it is truly mind-boggling how many they killed), odds are every single SS officer had murdered at least one civilian in cold blood. They don't deserve any pity from us.
