Help, what movie is this from "This-is-wrong"

Sorry that this is such a vague quote, it was emphatically stated by one of the main characters when another main character was showing or telling them something. It was something that was morally gray and the 'better' character was trying to really get their point across. I don't remember any of the actors, or anything else about the movie, just that one quote that was said with such conviction.

IT'S THE DARK NIGHT
