How is Nick's attitude toward Gatsby ambivalent even at the moment when he says goodbye to him?

The
following day after the argument in the city and Myrtle's death,visits Gatsby's home, where he
tells Nick the truth about his past relationship withand provides insight into his background.
As Nick is leaving Gatsby's home, Gatsby mentions that Daisy might call him later before he says
goodbye to Nick. Nick responds by telling Gatsby goodbye but turns around before walking away to
say,

Theyre a rotten crowd . . . Youre worth the whole
damn bunch put together. (Fitzgerald, 164)

Nick
experiences ambivalence when he contemplates 's character after saying goodbye to him for the
last time. It is significant that Nick also mentions,

It
was the only compliment I ever gave him, because I disapproved of him from beginning to end.
(Fitzgerald, 164)

Although Nick is disgusted by Gatsby's
affiliation with the criminal underworld, his ostentatious materialism, and his decision to
cover up Daisy's involvement in Myrtle's death, he has an affinity for Gatsby and believes that
he has a genuine heart. Nick views Gatsby as a hopeless romantic with honorable intentions and a
pure soul. In a sense, Nick feels that Gatsby has become a victim of the "foul dust"
that preys on him and disapproves of the people who take advantage and use Gatsby. Nick's
conflicting feelings involving his love for Gatsby and his disapproval of his life choices
result in his feelings of ambivalence when he says goodbye to him for the last
time.
