“‘You can’t judge Mr Kurtz as you would an ordinary man. No, no, no! Now–just to give you an idea–I don’t mind telling you, he wanted to shoot me too one day–but I don’t judge him’ […] He declared he would shoot me unless I gave him the ivory and then cleared out of the country, because he could do so, and he had a fancy for it, and there was nothing on earth to prevent him from killing whom he jolly well pleased” (162-3)
The Russian man’s description of Mr Kurtz reminds me of the character Tuco from Breaking Bad Season 2 (Tuco is a powerful drug lord that is seemingly insane. His friend/business associate “dissed” him, so Tuco beat him to death with his bare hands). Like Mr Kurtz, Tuco is not an ordinary man and does not have the rational of an ordinary man. Both characters use power, intimidation and murder to get the products they desire. Conducting business with Tuco and Mr Kurtz is so dangerous that even their “friends” lives are at risk. This passages suggest that ivory is not the only thing Mr Kurtz fancies, he also fancies power.
