Who was to blame for the death of Curley's Wife in the novel 'Of Mice and Men'?

Curley's wife is one to blame. I had to write a essay in class for who is to blame for the tragedy that happens to Lennie at the end, and Curley's wife is the reason. First of all, Curley's wife was stupid to tell Lennie to touch her hair, "I know lets let a giant man who has a tends to kill things by over petting them because there soft touch my loverly soft hair" Second, when Curley's wife started shouting and Lennie said oh be quiet, don't shout, George will make hell for me, she shut of shut her trap. If she would have listened to Lennie and didn't shout, Lennie would have not paniced and try to make her quiet by smothering her, and ending up breaking her neck, which killed her. Hope that helps
