How does the paragraph in Chapter 8 starting, "I’ve always been glad I said that" extend the paradox of Nick's feelings on Gatsby, The Great Gatsby?

The central paradox in Nick's feelings about Gatsby
centers around Nick's values and how Gatsby's life violates those values. A paradox is a
thing that seemingly contradicts reality while upholding it after all. Nick says that
Gatsby “represented everything for which I have an unaffected scorn.” This is because
Gatsby's life is the opposite of everything Nick professes to value and build his life
upon. Yet, when Gatsby asks Nick to do him a favor and host a tea party for Daisy, he
paradoxically does. When Gatsby needs a friend and confident, Nick paradoxically allows
Gatsby to turn to him. When violence and a crime are committed, Nick paradoxically takes
no steps to sort it out for the police. The reader is forced to ask how Nick can behave
in this paradoxical manner, how can he stand by watching--even participating--while
Gatsby and the others including Myrtle, violate the moral values that make Nick scorn
them? One conclusion is that perhaps Nick's values aren't what he believes them to
be.

The paragraph in Chapter 8 that begins with, "I’ve
always been glad I said that. It was the only compliment I ever gave him, because I
disapproved of him from beginning to end" extends the paradox of Nick's feelings about
Gatsby following Daisy's murder of Myrtle. Gatsby confesses to Nick that Daisy was
driving and that he, himself, will take the blame for being at the wheel when the police
trace his rather unmistakable car. Nick sees the nobility of the decision and the
finality of Nick's dream following the hit-and-run and an afternoon during which, in
front of his mistress, Tom gets Daisy to renounce Gatsby and cling to him. While the
paragraph begins with Nick's denunciation of Gatsby, it ends with a sympathetic picture
of him as Gatsby stands on "those steps, concealing his incorruptible dream," while all
those who accept his hospitality are waved goodbye.

Once
again, Nick has revealed his paradoxical feelings, based as they are on his values, and
extends the paradox: he denounces Gatsby and is paradoxically sympathetic toward him and
his failed life at the same time. The question thence arises as to the reality of Nick's
professed values. Does Nick have another set of unrecognized values that puts humanity
ahead of acts of corruption and therefore explains the paradox, since a paradox
seemingly contradicts reality while upholding it after all. This is yet another way the
paragraph extends the paradox of Nick's feelings about Gatsby: it extends to
paradoxically include Nick’s values that the paradox is bred from and based
upon.
