Heart of Darkness question?

Question

In Heart of Darkness, what the hell does this interpretation of Kurt'z famous speech mean? “The horror, the horror” could be a precise condemnation of himself and what he done, hence an affirmation of socially inculcated restraints.

Answer 1

It's deliberately ambiguous. He could be referring to himself, or what he has done, but it could also be a reaction to society's "rules" being a systematic denial of the baser side of man's true nature, and it could be his reaction to fully facing the reality that man is really no less a beast than any other animal.

They're all true, so maybe it's all of them.
