One of the most interesting and surprising decisions by a character in the novel To Kill a Mockingbird was made by Atticus’ son Jem. At one point in the story Atticus is guarding the jail, trying to protect his client, Tom Robinson. An angry mob of racist townspeople approach the jail, demanding that Atticus move out of the way so they can get to Robinson. Atticus refuses to do so, and the situation becomes tense and dangerous. During the confrontation, Atticus’ children, who have been spying on the scene from the cover of trees and bushes, run to Atticus’ side. When Atticus orders Jem to go home, Jem refuses. This is the first and only time we see one of the children directly disobey Atticus. It is an example of how much they love him, that they would be willing to take such a risk.
Another important decision and action occurs when Calpurnia takes the children to her church, the black church, in Maycomb. This gives Jem and Scout a chance to see part of the African-American culture that is so important in Maycomb. They witness both good and bad things on their trip, as a few churchgoers resent the presence of whites at their church, but most are gracious and accepting.
One important decision that Atticus makes is to defend Tom Robinson. This ultimately put his family in the center of the conflict of the story and led to his children's attack.
Another important decision in the story is when Jem decides to go back to the Radley place and fetch his pants that were ripped off on the fence. He risked being shot at but was spared of his father's disappointment.
