THEMES:
We vs. I:
Society vs. Moloch:
People vs. Owners/Businessmen:
Anger:
-Tom's anger when Casy gets killed. He has been angry before the book when he murdered someone with a shovel which landed him in prison. Anger of the people, they will rise up and overthrow the owners. Anger is a good thing, and by turning fear into anger is a great strength. Ma says that he needs to get a hold of his anger, or else he will change sides. 
Strength of Women:
-Character of Ma, Rose of Sharon's transformation in the end/coming of age, Ma keeps family together and transforms into the leader as the story progresses since Pa starts to dwindle and become consumed by self-doubt. Ma when she hears about Ruthie and Winfield, taking the discipline into her own hands and tells them all not to worry as she will venture out and to warn Tom. Ma attempts to handle many situations without the help of Pa. She rides in the back of the truck with Grandma's dead body without telling everyone that she had been dead for hours. 
Importance of Family/Change of the Definition of Family:
-Family sticking together throughout the hardships, change of definition comes when family goes further than just blood relation, but those who are suffering along with you and share the same plights, all the people who are migrant workers, Ivy and Sairy Wilson coming along the road with the Joads, Jim Casy's philosophy that turned him away
Pretty Boyd Floyd:
-Famous bank robber that took from the rich and gave to the poor, the 1930's Robin Hood, and the people almost worshipped him for his heroic generosity, symbol of the hard times, he must become a criminal in order to survive pretty much, he cannot survive with the limited work because he too is a lower class 'Okie' and must do what he can to support his family just like the rest of the people.
Moloch = God of Capitalism (idea) Capitalism is destroying people and paving the way for selfishness and allowing big businessmen to rule the world.
The One-Eyed Man:
-The man in the junkyard who hates his boss. He doesn't like to do anything because he has so much self-pity, using his deformity as an excuse. Symbolizes what Steinbeck DIDN'T want people to do in the tough times. Using excuses, such as a horrible boss and a missing eye as a means of giving up on life.
The Plague!:
-The Plague can be the dust storm, while it can also be the tractors that take over the land of the Oklahoma farmers, taking away their livelihood and way of a self-sufficiency. The amount of migrant workers coming from Oklahoma to California answering the yellow handbills to make some money, invading the new state.
Exodus:
-Exodus refers to the mass migration of a group of people. In the bible, it was the slaves and the Israelites travelling through the desert to the promised land. This book is heavily influenced by the bible,
Moses:
-He was the one who lead the Israelites who parts the Red Sea, Grandma represents Moses because she initially leads the Joad family to the 'promised land' yet is not allowed to see it. (She dies!)
Judas:
-Willy Freely, anyone who has sold themselves out to the big owners,
Handbills:
-The yellow handbills are a symbol of false hope. The owners use these to get many people to come for work so that they can pay very, very minimalistic pay. 
Hooper Ranch Incorporated:
-The worst place out of the bunch. The camp because the people know that the migrants need work and need food, so they pay very little and charge a lot for food/necessities. Almost like slavery in the way they totally control the tenant's lives, the exact opposite of Weedpatch Camp.
