How is Joshua's religion like that of the Pharisees?

The Pharisees were proud of themselves and they thought
that they were the only holy people. The Scriptures told them to love all people, but
they despised the underprivileged, looking down on them as sinners. Joshua is like them
in that he hates his own tribe instead of trying to help them change their ways. He also
believes that because the people of Kameno still followed the traditional way of life,
they were sinners.
