Fufilling Expectations Why?

Of the many characters in Great Expectations, the one that puzzles me the most is Able Magwitch. What I just cannot fathom is the amount of devotion he shows towards Pip. What fuel's that obsession to make Pip a gentleman. It can't just be that Abel feels indebted or that he sees himself in Pip. What makes this man forgo all thought of furthering his life to better the life of the blacksmith's boy. "Look'ee here, Pip. I'm your second father. You're my son-more to me nor any son. I've put away money, only for you to spend." ( 321)

Questioning Expectations

"...brought in by degrees some fifty adjuncts to refreshment, but of tea not a glimpse....which the waiter staggered in with, expressing in his countenance burden and suffering...and so from the whole of these appliances extracted one cup of I don't know what for Estella." (269)

Is this passage describing the fact that you can never recognize things you want after long periods of time, or is it speaking on the fact that you never get what you want from life right away, or a combination of the two? I honestly don't know what exactly Dickens is trying to get across, the first and last bits make sense but the added facts about the anguish of the waiter baffle's me. Please help me in my quest to understand this cryptic message.

"Great Expectations" proven Wrong

This picture shows a major point in the book, that there are two sides to every coin. When Pip envisioned London, all he thought of was the grandeur and the magnificence of it all, only to be disgusted by the slums and less desirable parts of the city when he arrives. "You may get cheated, robbed, and murdered in London. But there are plenty of people anywhere who'll do that for you." (169-170) For Pip this is a wake up call, not all things in life are pure and simple. Every good has its exact parallel evil, where there is the wealthy there is the poor, that's just the way of life. He finds that things aren't black and white,such as Wemmick. He isn't the most moral man alive yet, he's still a decent person. Pip begins to realize that things are rarely as we "expect" them to be, whether for better or for worse, ones "great expectations' are rarely proven true.
