Beside this, what flaw in Kurtz’s character leads to his downfall?
The most damaging flaw seems to be Kurtz’s loss of perspective: he came to believe his own hype and, rather than cut his losses and leave Africa with his health—both mental and physical—intact, he allowed himself to be trapped by the lies he spread.
Subsequently, question is, why does Kurtz say the horror? And now for those famous final words: “The horror ! The horror !” (3.43). Marlow interprets this for us, saying that these words are the moment Kurtz realizes exactly how depraved human nature is—that his inability to exert even a shred of self-control is the same darkness in every human heart.
Just so, why did Kurtz go to the Congo?
Kurtz is initially sent to the Congo to bring back ivory for the Company. Kurtz is obsessed with his own power. He can control men through his voice and his physical prowess, and has set himself up as almost a god among his men and the natives. Only his sickness causes him to lose that power.
What does Kurtz symbolize?
Kurtz symbolizes the far end of where greed can take you. Kurtz also represents the love of power the white colonizers have as well as the influence they have over the natives. Kurtz is the ultimate power at his Inner Station, and he sets himself up basically as the natives’ god, as far as ultimate influence goes.
