Why would Atticus have forced Jem to read to Mrs Dubose, even if the boy had not damaged the flowers?

Atticus explained to his children that Mrs. Dubose is an example of true courage. Even though she knew she was going to die, Mrs. Dubose wanted to be free of her addiction. Atticus tells Jem that courage is about more than men with guns. Instead, it is about knowing you're going to lose but sticking to your views and fighting anyway. Mrs. Dubose won, because she died beholden to nothing. Atticus calls her "the bravest woman I ever knew."
