In terms of the novel's overall thematic considerations, and the relationship between those considerations and Pao's journey of transformation as a character, there is the sense here that Pao is doing the wrong thing for the right reasons - protecting his daughter and preserving his emerging moral and personal integrity. It could be argued, in fact, that that's what he has been doing all along, providing for himself and his loved ones not only in the only way he knows how, but in the only way he sees possible.
