Yeah they do matter. And the central cast gives us eyes into their world. Upper class(Bruce, Talia, Daggett), Middle(Blake, Gordon, Foley), Lower (Selina, Holly, the Orphanage).
But you missed the point I was trying to make. Bale stated the film is about consequences. I am saying that Truth takes a large thematic part in the film as well. As the trilogy progresses, the people of Gotham become more aggressive as a consequence of Batman's actions.
