The Dead Gatsby

Well in truth if you want to be a douche you could say it was Daisy's fault for being the one that Gatsby fell in love with and the one he wanted to become rich for. But in truth it is her fault but not in that way. Instead of simply just telling Gatsby it was too late for him and letting him move on, she had an affair with him and when he thought she would leave Tom, she flipped back around on him because Tom manipulated her. That's when it becomes Tom's fault originally. It fully becomes his fault when he leads George Wilson to believe that Gatsby was the one having an affair with Myrtle and that he was also the one who killed her.
