Maus II

In "Maus II", Spiegelman makes it apparent that his father, Vladek, has trouble dealing with even the smallest issues of life.  On page 90, the second panel shows Art and his wife discussing Vladek's survival of the Holocaust:  "It's a miracle he survived.....In some ways he didn't survive."  The author almost questions the purposefulness of living through the Holocaust if your life is hell afterwards.

I find it also interesting that the first panel on page 90 has Lucia saying "I'd rather kill myself than live through all that".  When in fact, Art's mother DID kill herself!  She physically survived the Holocaust, but mentally, died in the concentration camps.  Is the author questioning what it means to "survive"?
