Before the man died, the boy was caring for him, and it was meant for them to live the remaining time together somewhat calm, "The boy though he smelled wet ash on the wind. He went on the road and come dragging back a piece of plywood from the roadside trash and he dove sticks in the ground with a rock... but in the end it didn't rain."(McCarthy278) The boy and the man got to have a moment where they didn't have to worry about anything else but each other, which is important for the boy since hes about to be left alone in the world.
The man didn't really believe in anyone having humanity in them until he saw it in the boy, "I want to be with you... You can. You have to carry the fire."(McCarthy278) Before he died he wanted his son to know there was still hope.The fact the man was trying to reassure his son of there being goodness out there means he also believes in there being some kind of hope, "Goodness will find the little boy. It always has. It will again."(McCarthy281) Although the man has never been entirely honest with the boy giving him hope is the best thing going for him, him dying has made him want the boy to find goodness llikt the little boy.
Even through rough, times there will always be people whom have hope in humanity. McCarthys novel story shows this through The Boy, which with the help of his father and his death, his remain with his faith of humanity throughout the book.
