Answer:
George ends up killing his friend out of mercy.
Step-by-step explanation:
A friendship is tested by how poor migrant workers have an isolated life. George ends up killing Lennie out of compassion/mercy. Lennie accidently kills Curley's wife. Fear brings about the death of curly's wife and she is the one who was seeking out a friendship with Lennie. There is a lot of mistrust among the workers. They all think that Lennie is guilty of murder. They start looking for Lennie to lynch him. George knows the hiding spot, finds Lennie, kills him so that he will not be lynched by the others.
