Liesel's Maturity

As the novel progresses, Liesel Meminger grows from an innocent child to a experienced young lady. One of the areas that Markus Zusak is trying to emphasize through the novel "The Book Theif" is the experiences and knowledge of the children during World War II. As we watch Liesel, we discover that many of the children during World War II grew from having no thoughts towards the conflicts to having more experience than any adult.
On page 440, Liesel and Rudy travel from the titles "fruit stealer to bread giver." They, as the war comes to a climax, discover that even though they may need help, other people are in worst conditions. The Jews, gypsies, homosexuals, and more are placed in concentration camps and treated like animals. They barely receive food, if any, the food they receive is stale bread. Liesel comes to find that there are more desperate people suffering from this devastation.
On page 443, Rosa presents the "Word Shaker" collection to Liesel. Rosa and Max "think [Liesel has] always been ready." Rosa examines her foster child grow up, just like Death, just like us. Ever since Liesel arrived at Rosa's door, she has been ready to face the challenge soon to come. She may not have understood the war, but as time grows older, Liesel becomes more involved with the ideas and thoughts transferring toward the second World War. In a sense, Liesel, as well as many other children, has a right to know the tragedy going on around her. She shouldn't just be standing there dumbfounded by the scenery, as dramatic as it may be. The children will lead the world one day, and they have a right to experience and brainstorm ideas, problems, and solutions to help the future flourish.
