Brody's always wanted to do what's right. That said, the question is what is right? He joined the Marines and shipped out to the war, presumably, to fight the good fight. After his years of captivity and conditioning under the sway of Abu Nazir, he still thought he was doing right in his attempt to assassinate Vice President Walden. And this week, in "The Clearing," he again tries to choose the noble path when he takes Dana to the police to report her hit and run.
