I sort of answered this question here. Basically, people were just glad that the war was over. Much of Germany was literally in ruins. There were more pressing matters than discussions around guilt. You also have to remember that being in the party and / or a supporter of the regime wasn't some niche thing, you had millions of enthusiastic supporters through all social classes. And then you had all the people that had do cooperate with the regime just as a part of their daily life. And then, even those that didn't explicitely cooperate, weren't they also partly responsible since they didn't do anything against the regime? ("Mitläufer"). The amount of people in Germany with genuine anti-Nazi credits was very small, it was mostly people that had already emigrated before the war. And then you had all the soldiers that had wittnessed unspeakable horrors in the war that didn't want to be reminded of any of that. So you had an incredibly strong atmosphere of guilt and repression. It's difficult to overstate this, my grandmother was born in 1933 and witnessed the end of the war in her small village and the following forced-relocation by the allies. Even though, as a child she didn't bear any personal guilt, in her 85 years of life she never once talked about the NS period, the war and the aftermath with my mother. And this is not unusual behaviour, most people from the baber boomer generation never quite learned what exactly their parents did from 1933-1945. So in short, everything about the Nazi period was heavily supressed and repressed directly following the end of the war. As I've said in my older post, the allies tried to force a public conversation and re-education but ultimately couldn't break through the public trauma / repression, it was only with a new generation growing up that a public conversation emerged.
