What might account for jems change of heart?

Answer 1

Jem's faith in justice and in humanity is badly damaged, and he retreats into a state of disillusionment. This eventually leads to his change in heart later on in the novel

Answer 2

Jem's change of heart in "To Kill a Mockingbird" may be due to his growing understanding of the injustices and prejudices in society, particularly towards African Americans. Witnessing the trial of Tom Robinson and his father's unwavering commitment to justice likely influenced Jem's moral development and empathy towards others. Additionally, Scout's perspective and experiences could have challenged Jem's initial beliefs and led to his change of heart.
