It’s complicated. Some old enough to have lived through the Third Reich feel some guilt. For younger generations, there isn’t guilt; instead, an acceptance of having to know the truth of what their ancestors did or didn’t do while knowing they are not to blame for their ancestors.  There is also the tangible national responsibility most Germans feel about preventing evil from triumphing again. Nowadays, most Germans shun Nazism and disagree with the Nazi regime and the crimes it committed up to and during World War II.
