What is revealed about the creature's character very early in chapter 15?

While the satchel furthers the creature's knowledge of civilization, and of the triumphs and sufferings of men, it also, in his own words, teaches him to "admire the virtues and deprecate the vices of mankind." One might describe this as a moral education; that is, the creature comes to distinguish between good and evil, and to look upon the former as preferable to the latter. Paradise Lost is the most important of the three books with regard to the creature's burgeoning morality. Milton's poem concerns itself with the struggle between God and the Devil, which is, at least in the Western imagination, the most important, most epic battle between the forces of good and evil.
