Reading your thoughts on Gastby was pretty enlightening. I agree with all of what you said. I too think that Gastby in his courtship of Daisy, he was in turn tainted, Corrupted like the question says. In his attempts to win over Daisy, Gatsby reduced himself and his morality by declining to the level of the majority of the other characters. Gatsby works and works to win over Daisy, but I agree very much that Gatsby is indeed morally bankrupt by the end of the story.
