What is the tone in chapter five in The Pearl by John Steinbeck?

Chapter 5 of the novel The Pearl, by
John Steinbeck, basically consists on the climax of the story of Kinoand Juana.  In this
chapter we can sense an overall tone of frustration, persecution,  and chaotic paranoia.
After all, this is the part of the story in which Kino's life gets completely turned
upside down

First, we see that Juana has awoken before Kino
in order to dispose of the pearl without him knowing. Already, we see the first
frustrated attempt to help their situation when Kino finds out, chases her and, to make
matters even worse, he physically batters her for the first time in their
marriage.

Second, we there is yet another frustrated
attempt by Kino to keep the pearl safe when he gets assaulted on his way home. The
result of his altercate is that he stabs and kills his assailant, and loses the pearl
temporarily. It does not matter: Kino will have to pay for the crime of murder whether
he has the pearl or not.

Third, Kino and Juana literally
lose their home, as they now are marked people, and need to escape. As they take refuge
in Kino's brother's house, they realize the weight that the pearl has in Kino's life- he
feels as if it is part of his soul. However, even he realizes that everything that he
has done is futile. All attempts continue to become frustrated, and he has become an
object of persecusion.

Therefore, frustration, futility,
and the chaotic feeling of fear and paranoia color the chapter with climactic
tones.
