What makes Atticus Finch such a good father?
Atticus is a good father for several reasons. First, he is honest with his children. He treats them as equals and doesn't really try to shelter them. Instead of sugar coating the trail, he is honest with Jem and Scout about it. One of my favorite examples of this is when he explain to the children how he had to take the Robinson case because if he didn't, he couldn't expect them to ever mind him again. He always practices what he preaches.
Second, he is empathetic. He always reminds the children to not judge someone until they have tried to see things from another person's point of view. Look at how Atticus handled Jem's run in with Mrs. Dubose. Or how he calmly reacts to Bob Ewell spitting in his face. He is always trying to set a good example for his kids.
Atticus is just and fair. He doesn't judge people based on race, gender, or other aspect of their being. What's more, he teaches his children to be the same way.
He is also an excellent role model in society--not just for his own kids, but for adults as well. This is to be respected and honored since it took immense courage to be this way in the time period of history in which this story is set.
