How does Nick feel about Tom and Daisy now? What kind of people does he say they are? Why?

Nick wasn't impressed either way.... he didn't like Tom. Likely, he didn't like Daisy. He found them to be careless..... wreaking havoc on the lives of others without thought to the repurcussions or consequences.

I couldn’t forgive him or like him, but I saw that what he had done was, to him, entirely justified. It was all very careless and confused. They were careless people, Tom and Daisy — they smashed up things and creatures and then retreated back into their money or their vast carelessness, or whatever it was that kept them together, and let other people clean up the mess they had made. . . .
