MAUS II First Half

After the discussion, I feel that so far in the reading that most of my questions have been answered to some extent.  The primary thing that I am still unsure of is how Vladek felt guilty after Auschwitz as described by Art's therapist.  This, I hope, would bring a better understanding to the character of Vladek when he talks with his son, not only about the Holocaust, but also concerning life in general.
