But then greed gets in the way. His insatiable hunger for ivory drives him to make alliances and enemies among the native Africans, raiding village after village with the help of his African friends as he searches for ivory. His obsession takes over so much that Conrad/ Marlow even describes him in terms of the material he seeks: his head "was like a ball—an ivory ball" (), and when he utters his final words, he carries an "expression of sombre pride" on his "ivory face" (). The jungle has "got into his veins, consumed his flesh" (), making him into a totally different man.
Because this is a debate, though, there's another side: the side of people that argue that this Africa-as-myth nonsense isn't Conrad speaking, but Marlow. Marlow isn't getting any gold medals for heroism or even truth-telling—he's a flawed character, with a flawed view of the world. There are tons of other first-person narrators that believe and do terrible things—think of Mersault , or Humbert Humbert . We don't take the character of Mersault as proof that Camus believes that killing is a-okay, or the character of Humbert Humbert as proof that Nabokov thought molesting kids was fine.
