In my view, any comparison between SASless and the SS is invidious; it's too easy to make sweeping generalisations and tar(nish) everyone with the same brush.
To elaborate, I'm not convinced that the entire SS condoned the cold-blooded summary execution of incapacitated, unarmed POWs and the attempted concealment of such acts in the certain knowledge that they contravened the Geneva Convention and LOAC.
