What is the difference between Bob Ewell and Atticus?

They were both men. That's about the only likeness I can think of. There was absolutely nothing about them that was similar, save perhaps height. Atticus was a gentleman; Ewell was a fiend. Atticus was right handed; Ewell was left. Atticus loved his children with all of his heart; Ewell beat his daughter black and blue. Atticus stood up for what was right, no matter how hard it was; Ewell was a liar, a cheat and a dirty mouth. Atticus had courage; Ewell was a coward.
