What is Atticus actually condemning is his closing remarks to the jury and what is the target of his final plea?

He is condemning 3 things at once, the society, the law, and the racism within the town. If Tom was white, this trial would be much different. Atticus has provided every single proof that shows that Tom was in fact not guilty and he should be free, but because of the scheming white society and the prejudice they hold, he was wrongfully acquitted. He begs them to do the right thing in the name of God, yet even then his plea is unheard. However, one person voted yes for Tom and this showcases a new start of an era.
