Paragraph 3
Furthermore, 
(1)
when Magwitch, the convict,
apologises to Joe on the marshes for having stolen a
dram of liquor and a pie from the smithy (Magwitch
here is protecting Pip who has been responsible for
taking them), Joe shows his natural sympathy and
humanity by saying, ‘we wouldn’t have you starved
to death for it, poor miserable fellow-creatur, would
us, Pip?’ 
(2)
Pip learns a lesson here about showing
kindness to the most wretched of human beings, a
lesson he will in time forget and only remember
when he has reached a low point in his own life. Pip
feels his first feelings of guilt about Joe when he is
unable to be honest with Joe about having stolen the
file from the smithy. 
(3)
This is the first real sign of a
rift between the two, which will gradually increase
to a chasm.
