Final answer:
Tom Robinson from Harper Lee's 'To Kill a Mockingbird' is killed while trying to escape from prison after being wrongfully convicted, and Atticus Finch explains that Tom lost hope in the justice system.
Step-by-step explanation:
The question appears to relate to a character named Tom from a literary work, and how that character was killed. Without specific details, it is difficult to accurately determine which Tom the question refers to. However, the mention of Atticus suggests that this question could be about Harper Lee's novel To Kill a Mockingbird, in which case, Tom Robinson is the character in question. Tom is falsely accused of raping a white woman and is tried in court. Despite evidence proving his innocence and the efforts of Atticus Finch, Tom's lawyer, he is found guilty. Then, while trying to escape from prison, Tom is shot and killed by the guards. Atticus explains that Tom ran out of hope and decided to take the chance of escape rather than waiting for an appeal with a very slim chance of success.
