Is it really much comfort to say: well, at least we're not rounding them up into death camps?

I don't find people do much discriminating between different groups of Nazis. The infantry perpetuated violence and death just as much as the death-camp members. After all, what do you think they did to the newly-conquered populations those polite infantrymen rounded up?

There's also a difference between the world 100 years ago and today. We live in a more civilized, more peaceful time. The violence in Iraq is some of the broadest and most destructive of our day.
