Charlie demonstrates how kind and caring he is by expressing concern for Veruca. It doesn’t matter to him that she was rude and selfish—he still doesn’t think she deserves to die in the incinerator. The Oompa-Loompas, meanwhile, back up what Charlie’s grandparents have been saying throughout the novel: that it’s a parent’s responsibility to step in and correct their children when they misbehave. Parents, in other words, can create “brats” like Veruca—or they can create good, virtuous kids like Charlie.
