Her remark was not only lunatic - it was obtuse lunacy. I have no idea what she was saying. That Pearl should not have proclaimed his religion - it was divisive? That beheadings are a good way to reconciliation?
She was trying to blame Pearl for his own beheading.
Perhaps that every Jew should take personal responsibility for all the sins of the world, and allow themselves to be slaughtered on the altar, to seek atonement, and put an end to the “cycle of violence”.
