Final answer:
Atticus Finch believes that all men should be equal before the law, which reflects the ideals of the Declaration of Independence and the American justice system, advocating for judicial fairness and an equal opportunity to justice for all.
Step-by-step explanation:
Atticus Finch, in Harper Lee's 'To Kill a Mockingbird', subscribes to the belief that all men should be equal before the law. This is a fundamental principle that echoes the sentiments expressed in the Declaration of Independence and the notion that every individual, regardless of race, religion, or background, is entitled to the same judicial fairness and civil rights.
Atticus's view of equality is in line with the moral and ethical underpinnings of the American justice system, acknowledging that while people are different in abilities and circumstances, they all should have an equal opportunity to justice and fairness.
