I am quite skeptical as to „never“. The example you give is an infuriating one and there are too many of those. But that there has been no discussion about de-nazification is simply not true. In academia the topic definitely has been dealt with. See for example this article by the Centre for political education [0] which I consider an example of making this available to the public.
Also these efforts didn’t happen in a vacuum, Europe and Germany was in ruins, the allies wanted to wrap them up as well. Ironically the Sowjets were more drastic than the Western allies with their efforts, and we’ve ended up with a second totalitarian regime in Eastern Germany. They’ve even re-used the concentration camps.
Anyhow. I remember talking about this in school and critically discussing the History of Germany in the last century. We must not forget, we must not repeat.

There has never been a serious discussion in Germany about its failed post-WW2 denazification programme, history got in the way. Just yesterday I was on the wikipedia page of the first commander of the Gestapo, a certain Rudolf Diels, only to learn that immediately after WW2 he led quite a peaceful life, perfectly integrated in the German state institutions:
> After 1950 he served in the post-war government of Lower Saxony[3] and then in the Ministry of the Interior, until his retirement in 1953.
Like, what the hell?
Even on the economy side you've still got BASF and Bayer happily doing business of hundreds of billions each year, while suffering almost no economic repercussions as a result of their role in WW2.
One of the few Germans from the public sphere that I know of and who really wanted to confront this problem head on was Heinrich Böll.
