Neither the Finch nor the Ewell children have a mother. However, their lives are totally different.Compare and contrast the similarities between...

There are many, many differences between the Finches and
the Ewells, despite the fact that neither family includes a mother.  Atticus Finch does
his best to teach his children the importance of morals and ethics while modeling them
himself; Bob Ewell sets an example of laziness, lying, and taking advantage of others
whenever possible.  Atticus Finch loves peace and controls his temper, while Bob Ewell
does his best to draw attention his way, even when he must resort to violence to do so. 
The head of the Finch household attempts to show his children love and kindness in every
way possible, but Bob Ewell seems to have no compassion or tenderness for his
offspring. 

In addition, Bob Ewell demonstrates no respect
for others and believes himself to be superior to those around him, which directly
contrasts Atticus Finch's efforts to treat everyone (Boo Radley, Tom Robinson, the
Cunninghams) with respect and does not consider himself to be superior to anyone.  Bob
Ewell is willing to do whatever he feels is necessary in order to get his way and make
others see him as a peer, but Atticus does not feel the need to prove himself to those
who judge him.
