Heart of Darkness prompt 6

The postscript Kurtz left on his writings, "exterminate the brutes!" seemed to seriously contradict the perviously expressed ideas in the body of his papers.  His writings focused on the civilization and incorporation of natives (or uncivilized people) into civilization.  His work started out with the right idea and good intentions, but it seems his insanity, among other things, sent him into a spiral with no real means of an end.  Kurtz seems to be a very contradictory human being; he supposedly is in the inner station making great advancements and headway.  He is said to have been doing good and making relationships with the people, but when Marlow arrives at the inner station, there are decapitated heads decorating Kurtz's dwelling.  This seems to be the real savagery of the novel, not the natives themselves.  Kurtz's last words, "The horror! The horror!"  could be interpreted as meaningful, or meaning nothing at all.  While on the brink of death, Kurtz comes to grips with the fact that he has virtually done nothing that he originally set out to do.  If anything, in the apparent process to civilize the uncivilized, he deteriorated himself.  He became the savage; the uncivilized one.  This realization sends him into a frantic rush to get all of his thoughts and ideas out to Marlow.  If he can put this load on Marlow, he won't feel as bad for his absolute failure.  The horror could be this very realization, but the reader can never know for sure.  It could just be another crazy outburst or pain felt during final moments of his life.
