Innocent people are dying in both stories. Because of prejudices between two families, Romeo and Juliet both die. Sadly, two beautiful young people lose their lives because two families cannot get along. The prejudice is unnecessary. By the end of the story, two families unite because of Romeo's and Juliet's deaths, but it is too late to bring their children back.
The Montagues and Capulets promise to end their hostilities, which have caused the deaths of their only children.
In To Kill A Mocking Bird, Tom Robinson dies because of prejudices. He is condemned for a crime he didn't commit. In Maycomb, there is so much prejuduce against blacks. Tom Robinson does not stand a chance in the town of Maycomb because he is black.
Both these stories are based on the cruelty associated with prejudices. Because people are ignorant in their prejudices, Romeo, Juliet, and Tom Robinson die. It is a senseless shame that other people's prejudices could cause innocent people to suffer death.
