A Clockwork Orange
The resident priest of Staja, the prison chaplain genuinely finds Alex endearing. He also likes Alex because he is a snitch, and the snitching provides fodder for the chaplain moving up in the world. A hypocrite, this religious man seems to be always drunk on Scotch and smoking cigs. What's worse, though, is that while he gets all righteous atop his sermon mount, he buries his principles and morality for his professional ambitions. He adamantly opposes the State's endorsement of Ludovico's Technique, but never speaks up against it except to Alex.
