I need help contrasting Bob Ewell and Atticus Finch in the book To Kill a Mockingbird.

In Harper Lee's To Kill a
Mockingbird, comparing Atticus Finch to Bob Ewell is like comparing God to
the devil. No two characters that I can think of are so diametrically
opposed.

Atticus is a man of integrity. His moral compass
not only guides his actions, including his respect for the dignity of others, but it
keeps him grounded as he tries to guide his children in a sometimes-ugly, and often
changing world. Atticus is humble and respectful of everyone, even Bob Ewell. He
refrains from speaking badly of anyone, and he believes that people should assume
responsibility to help the world, as well responsibility for their actions. Atticus
tells the children that before they judge, they need to walk around in someone else's
skin for a while; in this way they better understand others and themselves. Atticus is
very concerned that his children will always be able look to him for guidance and with
respect—something he expects he must earn. He believes, too, in protecting the weak: the
mockingbirds—which include Boo Radley and Tom Robinson.

Bob
Ewell, on the other hand, is a poor excuse for a human being. He does not care for his
children: he is abusive and sees to his need for alcohol before his children's need for
food or clothing. He is vulgar and crass, as we see in the courtroom. He is a liar and a
bigot, with no respect for the truth or for other people. He does not work, but the
money he gets on "assistance" he drinks away. He is not interested in setting an example
for his children, as we see with Burris Ewell when Scout starts school. Bob is a bully
and would-be murderer.

Sheriff Tate shares his opinion of
Bob Ewell with Atticus stating that there are some people that should just be shot and
done with it, and one of those people is Bob Ewell.
