Toward the end of the film, Rogers is giving a pep talk to a room of traders, “People are going to say some very nasty things about what we do here today, and about what you’ve dedicated a portion of your lives to,” he tells them. “But have faith that in the bigger picture, our skills have not been wasted. We have accomplished much, and our talents have been used for the greater good.” This is a man doing something he knows is wrong, and not just that but wielding his power to make dozens of other people do something he knows is wrong. The brilliance of the movie is its illustration of why he, and so many like him, make that choice, again and again and again.
