“Would they have fallen, I wonder, if I had rendered Kurtz that justice which was his due? Hadn’t he said he wanted only justice? But I couldn’t. I could not tell her. It would have been too dark – too dark altogether…”
Conrad, Joseph. Heart of Darkness and Other Tales. “Heart of Darkness”, 186. Oxford: Oxford NY, 2002.
Conrad might be making a remark about literary modernity at the end of his story, and his frustration with deciding whether to tell people the truth through his writing, or tell them what they want to hear.
