This is nazi apologia. I mean like actual, 1945, "guards at Auschwitz" nazis. A lot of Germans developed psychological problems due to their crimes against humanity. It's why they created death camps. And they all claimed they were "...just following orders." Many more claimed it was a "necessary evil to eliminate the Judeo-Bolshevik hordes."

Despite all this, nazis still got hanged after the war (especially if they were caught by the soviets). We can list Germans who didn't commit atrocities or actively fought against the genocide being carried out. There's hundreds of them listed on Wikipedia alone. The Germans knew what they were doing was wrong. They ignored morality because they wanted an excuse to steal from and kill their neighbors.
