Boo Radley, the mysterious and reclusive character from Harper Lee's To Kill a Mockingbird, saved the children, Jem and Scout Finch, from Bob Ewell's attack.
Boo's actions were driven by a deep sense of protectiveness and loyalty. He had observed the children's encounters with Ewell and understood the danger they were in.
Boo's actions were also motivated by a desire to right a wrong. He had been wrongly accused and ostracized by the community, and he saw an opportunity to redeem himself in the eyes of the children he had come to care for.
Boo's actions were ultimately a testament to his goodness and compassion. Despite his isolation and the prejudice he faced, he chose to act selflessly and protect the innocent.
While Boo's motivations are complex and multifaceted, his actions highlight the importance of empathy and understanding in a community often marked by prejudice and fear.
