does Art Spiegelman have self-blame towards his mothers death?

Art's feelings of guilt over the death of his mother are also relatively straightforward. As told in the brief "Prisoner on the Hell Planet" interlude in Chapter 5 of Book I, Art feels responsible for his mother's suicide, believing it to be a product of his own neglect. His last memory of his mother - in which she asks him if he still loves her, and he responds with a cold and dismissive "sure" - is a painful reminder of this disregard. Though this particular form of guilt does not play a major role in the story, it is noteworthy in that Art feels somewhat similar feelings of guilt towards his father, who is still alive.
