How do the novel and the film The Reader deal with the questions of guilt, responsibility, culpability and shame?

In addition to viewing these themes from Hanna's perspective, one could also view them from Michael's perspective.  Michael is not sure how he should feel about Hanna's involvement in the fire and in the camp, and he seems to experience a sense of guilt at wanting to be sympathetic towards her.  Later, when the prison calls to ask him to help her after her release, Michael feels that he has no responsibility for Hanna now because so much time has gone past.  He was happy to have a distant relationship with her through the tapes, but he is reluctant to see her in person.  Michael's issues of culpability do not have to do with any legal matters such as Hanna's do, but he does question whether or not he is morally tied to any responsibility for Hanna's well being.  Throughout the novel, Michael experiences feelings of shame and disconnection, mostly having to do with being abandoned by Hanna.
