How has our understanding of Bernard changed from when we were first introduced to him?

Bernard was sort of an anti-hero at the beginning of the book. He was rebellious in a good way. He was smart, critical of society, and an unafraid defender of what is real: he even wants more from a relationship than sex! By chapter 6 he begins to change. Bernard obsesses about his cologne tap he left running back in the hotel room while being introduced to another culture that has many of the things he longs for. Bernard starts living vicariously through John Savage and then indulges in the very same lifestyle that he once riled against.
