He was certainly anti-Christian, but I wouldn’t know whether he believed in God. In any case having him pray in the Warsaw ghetto makes no sense to me. Are the implying contrition on his part? Are they forcing him to appear sorry from beyond the grave and against his will as a sort of punishment? Or is he praying for help in reaching the “final solution”?
As we always been told due to his current location he’s most likely praying for ice water.
