Honestly Yehudi, that's exactly the reasoning I as a German have problems with:
Communism - a good idea gone bad hence not so bad
Nazism - bad! bad! bad from the onset"
Fact is that most Germans saw the Nazi state as a good thing mainly (till the chicken came home to roost that is).
The majority of the Germans lived well under the Nazis, not feeling opressed at all.
Nazi-Germany managed till to the dying days to be one of the most developed countries on Earth.
Do you see it honestly as a redeeming feature of Communism that it was equally murderous to everybody?
The opressing, and subsequent murdering of the Jews wasn't sold only as "they have to be killed because they are Jews"
They were presented to the Germans as deadly enemies, as a group of world wide conspirationalists who suck the life blood out of the german people, and who did this since ages, not at least as being guilty of fabricating the first world war and guilty of the hated Treaty of Versailles, to opress and humiliate Germany.
Germany MUST get rid of them to be able to breath freely again...Comparable to the "bad bourgeoisie" who had to be murdered before the paradise of the workers and peasants could be build!
I don't see there any difference only that Communism killed more people at home than Nazism who was more murderous against non-Germans.
Maybe that is the reason why Nazism is seen as more dangerous, more hateful, the holocaust worse than everything else...the shown capability of maintaining a highly civilisational, highly developed society and still be extremely murderous against perceived enemies.
Whereas communist Russia was not much more than a backward, third world slaughterhouse eating it's own - not so dangerous?
