George and Lennie are discussing their goal for the future. They hope to keep a job and make enough money so they can buy a ranch with many animals.

Lennie's Death. Chapter 6, Page 105
Look acrost the river, Lennie an' I'll tell you so you can almost see it.
When in Weed, Lennie saw a woman in a red dress that he wanted to feel. He was very attracted to it and wouldn't let go. He couldn't help himself. The author uses the color red to symbolize things that Lennie can't resist (woman in Weed, Curley's wife, ketchup). In conclusion, when the author mentions red, it foreshadows something bad that will happen. Inability to resist temptations will cause problems.
Lennie was playing with one of the pups and pet it so hard that he killed it. This occurs at the beginning of the chapter when Lennie and Curley's wife are alone. Subsequently, Lennie also kills Curley's wife. The death of the pup was used to foreshadow her tragic death. Although he does not mean to, Lennie continues to kill. His innocence protects him from reality but hurts those around him.
George decides that he needs to kill Lennie. His death was not only tragic, but also symbolizes George giving up on his dream. He is not just killing his best friend. He realizes that he will never accomplish his dream and thus puts down his ideals by killing Lennie. This is not what either of them wanted. It is hard to succeed in a cruel world.
