How is the statement out of character for Nick?

Nick gives the novel's final appraisal of Gatsby when he asserts that Gatsby is "worth the whole damn bunch of them." Despite the ambivalence he feels toward Gatsby's criminal past and nouveau riche affectations, Nick cannot help but admire him for his essential nobility. Though he disapproved of Gatsby "from beginning to end," Nick is still able to recognize him as a visionary, a man capable of grand passion and great dreams. He represents an ideal that had grown exceedingly rare in the 1920s, which Nick (along with Fitzgerald) regards as an age of cynicism, decadence, and cruelty.
