The road Pages 94-118

Parallel: On pages 110 and 111, the boy and man have just discovered a basement or crawlspace filled with men and women who were trapped and presumably being eaten by the men and women who live in the house. Starting at the bottom of page 110, when they just discover the people, until the end of the middle paragraph of 111, you see the man reference god six times. 

Contrast: On the top of page 114, you see the man consider killing his son. I thought that this was a very interesting point in the book because his son has talked about dying and being with his mom but the father wouldnt let him and tells him not to think like that. At this point, the father has thoughts rushing through his head asking himself if he should kill his son. He even says "curse god and die" showing that he has given up and seeking gods help for survival.

Questions:

Why is McCarthy always describing the setting? Whenever there is a descriptive setting, it is always the same cold, grey, ash filled desciption as before. 

In the middle paragraph on page 96, it says "He fought back the rage, Usless". What is he fighting back?
