I have no idea this guy was "Christian" in the sense of being a deep believer in something resembling contemporary Christianity and a regular churchgoer, or if he's just "Christian" in a basic tribal sense like many people. Regardless, from what I've seen he's motivated by basic ethnic/racial tribalism combined with a belief in a Great Conflict and not by the belief that Jesus told him to do it.
Still I do love the right winger "if he did something I don't approve of he isn't really Christian" reasoning.
