er it is all to do with their own WW II heritage which involves saying what the Nazis did was wrong - and they are tray sorry.
we have more the idea - "if my father did wrong, have a word with him about it " ( my dear papa at the time of the Eichmann trial 1962).
(coonnected with blood guilt, about the jews being punished 1200 AD for the death of Christ) - and then, for killing and eating the Child martyrs ( Little St Hugh of Lincoln and a few others)
Note to mods: this is an ironic reference. i dont REALLY believe that....
