Your characterization of the nature of the Holocaust is too far off to be helpful. The broader German population did not individually kill Jews (unlike, for instance, the genocide in Rwanda where a lot of the deaths really were from neighbors killing each other).

Without some degree of widespread antisemitism, the actions that facilitated the Holocaust would not have happened--but from the perspective of the neighbor, the bank teller, the teacher, it didn't seem all that different from the internment of Japanese Americans in the U.S. during World War 2.
