My take is that Pip may be his "Father's" [brother-in-law's] son but regardless how the "mother" is depicted as a horror even in real life with a horror parent. the parent does have an influence and I think that without conscious recognition he liked what he saw at the house of Miss Havisham and the influence of his "mother" allows him to imagine he could live better and closer to how Miss Havisham lives. Toward the end of this frist bit it seems to show Pip as having eyes for Stella where as when he was a kid I think he thought she was special but not for him - he enjoyed beating her at cards and only kissed her because he thought that would please Miss Havisham.
His thinking of Stella toward the end I thought said more about how he thought he could have a life like the one he saw in the house of Miss Havisham.
I think this version has Miss Havishamshowing a reaction to life with a number of today's better known Psychological disorders - not necessarily crazy but things like - Post Traumatic Stress, that is life long - some of the avoidance behavior includes; A loss of interest in important, once positive, activities. Feeling distant from others. Experiencing difficulties having positive feelings, such as happiness or love. Having strong feelings of distress when reminded of the traumatic event. Feeling constantly "on guard" or like danger is lurking around every corner.
The symptoms of PTSD are difficult to cope with, and so, many people with PTSD develop unhealthy coping strategies, such as alcohol or drug abuse or deliberate self-harm. Miss Havisham appears to be self-harming herself and like many with PTS they inflict a form of their own trauma on others. Her disorders appear to include:
Dermatillomania (skin-picking); An Impulse-control disorders are those that involve an inability to control impulses, resulting in harm to oneself or others.
Depersonalization Disorder; Persistent or recurrent experiences of feeling detached from, and as if one is an outside observer of, one's mental processes or body (feeling like one is in a dream).
Oppositional Defiant Disorder; Deliberately doing things that will annoy other people, blaming others for his or her own mistakes or misbehavior, being touchy or easily annoyed by others, being angry and resentful, or being spiteful or vindictive. Negativistic and defiant behaviors are expressed by persistent stubbornness, resistance to directions, and unwillingness to compromise, give in, or negotiate.
