Changing perceptions of Boo Radley

My first impression of Boo Radley was that he was just a old fart that cared so little for the world outside of his rundown house that he chose to be kooped up in it until he withered away. But as the book progressed i realized that it wasn't his choice to be trapped inside the house and that he might be missperceived by the children. He attempts to show this multiple times by leaving peices of gum in the old oak tree for Scout, Jem, and Dill. I think that as the story unwindswe will find that Boo Radley is not as crazy as he seems and has a more compassionate side.
