The only character who is reminded of his guilt concerning the fate of Jay Gatsby is Tom Buchanan. Following Gatsby's death, Nick Carraway recalls running into Tom Buchanan one October afternoon on Fifth Avenue. Nick initially refuses to shake Tom's hand and proceeds to ask Tom what he told George Wilson. Nick reminds Tom of his involvement in Gatsby's death and Tom admits that he informed George that Gatsby was responsible for Myrtle's death. Tom experiences guilt and reluctantly tells Nick,
What if I did tell him? That fellow had it coming to him. He threw dust into your eyes just like he did in Daisy’s but he was a tough one. He ran over Myrtle like you’d run over a dog and never even stopped his car. (Fitzgerald, 191)
After admitting to telling George Wilson that Jay Gatsby killed his wife, Tom demonstrates his selfish personality by lamenting how Myrtle's death negatively impacted his life. Nick then refers to Tom and Daisy as "careless people" who destroyed things and simply retreated back into their wealth while other people cleaned up their mess.
Nick does not run into Daisy after Gatsby's death, and the only character reminded of their guilt regarding Gatsby’s fate is Tom Buchanan. From their conversation, it is evident that Tom feels somewhat guilty after Nick confronts him but insists that Gatsby had it coming. Overall, Tom and Daisy Buchanan are portrayed as completely selfish, callous individuals, who hide behind their money and refuse to accept responsibility for their actions.
