What are 10 films with a morale theme?

Um, I can only think of a few, Citizen Kane. I guess the morale is if you don't care about money and all you want is love, you have to make sure it's not only on your terms, because then the girl leaves you. Also To Kill a Mockingbird, about racism, Lolita, about pedophilia, and There Will Be Blood, about greed.
