Tom is a big helper to the people he cares about. When Casy is killed, he sort of avenges his death by attacking the man who killed him. Also, when Uncle John is drunk, Tom finds him and helps him back to their camp. "Tom got down on his knees. He put his hand on Uncle John's forehead, and it was hot and dry. John brushed his hand away clumsily" (Steinbeck 276).
