Some great weird west here. The religious underpinnings are good, and there's some solid metaphors for the good of all faiths to stand against the bad of any faith. Selective judgement is not righteous.
Good characterization, but I didn't really feel the relationship between the MC and Mr Hadj was strong enough for Mr Hadj to sacrifice himself just to save this stupid, impulsive kid.
I thought he made it pretty explicit that it wasn't done for the kid, but because of his mission of atonement. Saving the kid was a side benefit.
