My theme: Power vs powerlessness
Example: "Lennie obeyed him. George looked down at the gun." (Steinbeck 106)
This quote shows that Lennie is a character that has little power. When George tells him to do something, he does because he is afraid of what will happen if he does not.We see in the book that George can be very powerful. Lennie has little power because he does everything George says. He may be strong, but when it comes to making decisions, he is not the one in power. In the last chapter, Steinbeck shows how powerful George is when he takes the gun and uses it to kill his alliance. The theme of power vs powerlessness is evident in the last chapter.
So why did George kill Lennie any way? Check out this article to see for yourself!
