In the classic novel, The Grapes of Wrath, the Joad family, who was evicted from their land, decides to migrate out west to California for a chance at survival. John Steinbeck, the author of the novel, uses multiple literary techniques to convey the theme of brotherhood. Steinbeck uses the self-family-society motif, biblical allusion, and logical ending to portray this theme.
An example of character development is a character that evolves from self indulgence into caring about his or her family, and then finally society.

Tom convinces a trucker to give him a ride. Throughout the duration of the trip, the trucker questions Tom, which irritates him. Soon, Tom observes that the trucker was looking at him and noticing Tom's new clothes. This begins to agitate Tom even more and he reacts by crushing a grasshopper with his fingers. At this point, Tom only cares about himself preoccupied with the truck driver's annoying questions.
