One could argue that Tom Robinson's conflict with the Ewell family leads to Tom and Bob's death. After Tom is falsely accused of assaulting and raping Mayella Ewell, he stands trial against the Ewells and is wrongly convicted. Tom is then sent to the Enfield Prison Farm, where he is shot and killed while attempting to escape. Tom's death results in his children being raised without their father and makes his wife a widow.

During the trial, Atticus exposed Bob Ewell as a malevolent, abusive alcoholic, who sexually assaults his daughter. Bob Ewell feels as if Atticus ruined his reputation throughout town and attempts to enact revenge by harming Jem and Scout. Fortunately, Boo Radley prevents Bob from seriously harming the children and kills Bob during the altercation. In a way, both Tom Robinson and Bob Ewell lose their lives as a result of their conflict.

Atticus and his children also suffer as a result of Tom Robinson's conflict with the Ewells after Atticus decides to defend Tom in front of a racist jury. Jem and Scout also gain perspective on their prejudiced community by listening to their racist neighbors criticize their father and witnessing Tom Robinson become a victim of racial injustice.

Maycomb's racial inequality is exposed as a result of Tom's conflict with the Ewells and issues concerning justice are emphasized by the outcome of the trial.

Given that the trial of Tom Robinson, to determine whether or not he in fact raped Mayella Ewell, is arguably the central portion of the plot, there are quite a few results of this conflict.

One is that Atticus Finch is engaged as the defense for Tom Robinson. This creates a conflict with many people in the town but also provides the backdrop for Scout and Jem and others to learn about how Atticus feels about black people in their town and in general and how that differs from the attitude of much of the town.

It is also clear that the trial and Mayella's testimony served to highlight some of the problems in the Ewell family as she has a difficult time denying that her father abuses her and her claim of rape may in fact be her attempt to protect her from her own father after she reached out to Tom for affection.

In the end, one might also argue that the conflict between Tom and the Ewells leads to Bob Ewell's death at the hands of Boo Radley. After the trial and the embarrassment of it, Bob is set on hurting Atticus but he chooses to attack Scout since he is too cowardly to attack Atticus directly. Boo Radley intervenes and kills Bob.
