Final answer:
Atticus takes an ethical, respectful approach in the courtroom, while Mr. Gilmer uses emotional appeals that play on biases, showcasing contrasting styles of legal representation.
Step-by-step explanation:
The differences between Atticus and Mr. Gilmer in the courtroom are emblematic of contrasting legal styles and personal beliefs. Atticus, as depicted in Harper Lee's To Kill a Mockingbird, embodies an ethical and respectful approach towards all individuals, regardless of their race or social standing. With a commitment to justice and the legal system, Atticus treats witnesses and the defendant with dignity and works meticulously to defend his client, Tom Robinson, against the racial prejudices of the time. On the other hand, Mr. Gilmer, despite starting as a competent lawyer, exhibits a shift towards a prosecutorial style that dismisses fairness for emotionally charged rhetoric, akin to a revivalist preacher in the courtroom, swaying the jury by appealing to their biases rather than evidence.
Their demeanors in court highlight the profound impact a lawyer's conduct can have on the perception of justice. Atticus's fair-mindedness contrasts sharply with Mr. Gilmer's more manipulative tactics, revealing a broader commentary on the legal system's susceptibility to human flaws and societal pressures.
