Pick a theme from Great Expectations and describe how Dickens shows this theme by using characters and/or eventsGreat Expectations by Charles Dickens

Having been a lonely child himself who was made to work in a
blackinghouse as a boy while his father was cast into debtors' prison, Dickens often wrote about
orphans and their feelings of loneliness and alienation. In his novel, Great
Expectations, there are five known orphans: Pip, Mrs. Joe, Biddy, Magwitch, and
Estella. As orphans, Pip, Biddy, Magwitch, and Estella are all victimized by those who control
them. But, each of these characters deals with this victimization in
different ways.

• Pip, alone in the cemetery with the
  coarse man in grey, expresses human commiseration to this man despite the man's turning him
  upside down and issuing threatening oaths. When he goes to Satis House to act as a playmate for
  Estella, Pip feels great melancholy as he looks at the ravaged woman and her closed, dark house
  even though she exploits him as the boy with whom Estella can practice as Miss Havisham whispers
  to her, "You can break his heart." The pompous "swindler," Pumblechook, browbeats Pip when he
  stays with the corn chandler before going to Miss Havisham's. Later, when Pip is a young man,
  Pumblechook takes credit as Pip's mentor who has led him to being a gentleman. For a brief
  period, while he aspires to be a gentleman, Pip acts as the victimizer as he is cruel to Biddy
  and Joe; Pip stays away from home for eleven years, and when he first became a gentleman, Pip is
  cruel to Biddy. But, later Pip learns that having power is very unsatisfying and he returns home,
  the prodigal son, who is penitent.


• Estella reacts to her
  victimization by becoming very coldhearted and cruel, so cruel that she has no feelings for Miss
  Havisham, who has loved her in her own perverse way. "You made me," Estella tells the pitiable
  woman who cries as she realizes that she has made Estella absolutely heartless. Fortunately,
  however, Estella breaks the abuse cycle as she is victimized further by her husband Bentley
  Drummle by being a good mother to her child and by reconciling with Pip in the
  ending.


• Magwitch, also, ends the abuse cycle of his
  victimized/victimizer life as he risks his death to see his "dear boy" Pip, whom he has supported
  in his efforts to become a gentleman. Having been a gamin in the streets of London, living by
  theft, Magwitch chases his victimizer Compeyson until he finally wrestles with him in the Thames
  when Pip and Herbert try to get him aboard a ship. Before he dies, Pip tells this poor man who
  has suffered from the corrupt criminal justice system that his daughter he believed to be lost
  still lives.


• Perhaps the greatest example of a person who harbors
  no ill feelings for her victimization is Biddy. Whenever she is criticized by Pip, Biddy repays
  him with kindness. When Pip chides Biddy that Joe has not learned to read and write, Biddy
  counters that Joe has not had the heart to learn. Always she defends Joe whenever Pip criticizes
  him. After all that happens, Pip returns to the forge and Biddy is as gracious as ever to
  him.
