David's father shares his insight on page 156: "...I believe that in this world people must pay for their crimes. It doesn't matter who you are or who your relations are; if you do wrong, you pay. I believe that. I have to."

What do you think about these convictions? What other story does Wes share with David about himself? How does this story complicate his belief system

I think what David says is true and hes talking about Uncle Frank. Since Franks a loser and rapes indian girls he deserves to be in jail. This quote means that since Franks brother is the sheriff it doesn't mean he can do what ever he wants to do. Wes shares when Frank and his friends saved Wes from getting jumped by indians. Frank saved Wes but wes still needs to put him in jail.
