There is a lot already written on the subject - maybe it worth reading that stuff to get informed and well research background info.
Having lived in Germany for 18 months - the Germans are very aware of what their grandparents did. They are highly embarrassed by the legacy it has given them. Despite ill informed view points in the UK, they are well educated and well structured. They don't try and ignore the past -but after 60 plus years , they do feel value in moving on.
This doesn't mean that the far right doesn't still exist - go to Rostock and parts of the old East, there are still sympathies. As there is in Bavaria. But the vast majority of the population are liberal and forward thinking.
Did the people in general know during the Third Reich what was going on. Yes - of course they did. Sachenhausen is just out side of the main town, Dachau is a suburb of Munich ( thought it's purpose wasn't as a death camp). At the time many people in Grermany support Hitler because of the mess and the humiliation Germany was left in after the war. As did many Austrians, Dutch, French and members of the UK Royal Family.
But there is plenty of great stuff written about.
Be aware that the winners very rarely see their actions as being war crimes - but the Germans certainly feel that the targeting of civilians a Dresden was one.
Churchill sending the Cossacks back to Stalin at Yalta was another ...
But none of this stopped race hate in Rwanda, the Balkans and the Killing Fields ...
