When Roy offers to hook Joe up with a job in the Justice Department, we might think for a moment that he's a nice guy.
First we learn that he's borrowed money from a client (in itself illegal) and he's trying to weasel out of repaying the loan. Over the course of the play, we see just how wicked Roy can be. Based on a real-life communist-hating figure, Kushner's Roy is unrepentantly vicious while still managing to be a complex and interesting character. Roy Cohn, a powerful conservative lawyer, is one of best villains ever to walk across a stage.
