“I did not betray Mr Kurtz – it was ordered I should never betray him – it was written I should be loyal to the nightmare of my choice. I was anxious to deal with this shadow by myself alone, – and to this day I don’t know why I was so jealous of sharing with any one the peculiar blackness of that experience” (172).

Kurtz’s impression on others is shown here. I think this ties to how the natives saw him as a kind of deity, how he is to never be betrayed.
