Falling Action and Resolution
George kills Gatsby and himself, believing Gatsby was having an affair with Myrtle, and was responsible for her death. In the end, Nick is dismayed by the lack of remorse shown by Daisy and Tom, and by the all the people who used Gatsby. This final quote from Chapter Nine reveals Nick’s feelings:
I couldn't forgive him or like him, but I saw that what he had done was, to him, entirely justified. It was all very careless and confused. They were careless people, Tom, and Daisy — they smashed up things and creatures and then retreated back into their money or their vast carelessness, or whatever it was that kept them together, and let other people clean up the mess they had made. . . .
