Tom Robinson would be described as innocent, defenseless and harmless person. He was a scapegoat for Bob Ewell who was the actual person who raped Mayella. Since he was an African American, it was easy to blame him and accuse him on court. The judge will sentence him to jail without any thoughts even when the evidence is against mayella ewell. He is vulnerable when it comes to the law and racism against him, which simply made his life unfortunate, and all this happens because of his special identity: african american. He was the victim of racism and prejudice from the white people at that time.
There are a lot of quotes about justice after the Tom Robinson trial when the children are talking with Miss Maudie and Atticus. One example is on page 219. Atticus says, "Tom Robinson's a colored man, Jem. No jury in this part of the world's going to say 'We think you're guilty, but not very' on a charge like that. It was either a straight acquittal or nothing." Tom Robinson’s case helped Jem and Scout to understand more about the world.
