While Atticus does not meet the strict standards of a dynamic character, he does, nevertheless, undergo a chainge in attitude in Chapter 29 of To Kill a Mockingbird when Heck Tate convinces him of the justified reasoning that "Bob Ewell fell on his knife." For, in his discussion with the sheriff, Atticus comes to realize that there is more potential for evil in human behavior than he has hitherto be aware:
Atticus shook his head. "I can't conceive of a man who'd.... "I thought he got it all out of him the day he threatened me. Even if he hadn't, I thought he'd come after me [not his children]."
In another aspect of change involving Atticus, there is much that is revealed about his character to the children and the reader such as his markmanship with a gun. However, the change here is not in Atticus, but in Scout and Jem's attitude toward their father. So, the alterations in the perspective of Atticus must not be confused with a change in his consistently moral, honest, and humble character.
