Harper Lee included Miss Maudie as a main character in the novella killing of a mockingbird
because she treats everyone equal. Usually adults don't treat kids equal but Miss Maudie does. Evidence that supports my answer is " She called us by all our names". Another piece of evidence that supports my answer is "Miss Maudie benevolence extended to Jem and Dill whenever in pursuit". Miss Maudie is very important in this novel and is a nice person. Without Miss Maudie the children would not be getting treated as equals.
