What does Robert Ewell’s behavior towards his own lawyer suggest about his personality? What does his description of his daughter, Mayella, suggest about his feelings towards her?

Bob Ewell is having his "ten minutes of fame". He is cocky and ignorant in the courtroom. He thinks, unfortunately he is right, that he can't be convicted. Bob Ewell understands very little about the court process and uses his ignorance to entertain the people in attendance. Ewell expects his daughter to say everything she has been told to say. He treats his daughter in a creepy condescending fashion.
