who was affected by in curly's wife death?

All the men are tempted by her. She is the only young woman on the ranch and she uses her sexuality to entice the men. They fear her because she is Curley's wife (boss's son), they do not want to get fired. Her death directly affects Lennie and George. George must shoot Lennie. George will be alone. Their dream of a farm shattered forever. Candy's dream of joining them will be dead too.
