What is your own conclusion for Heart of Darkness?

My own conclusion is that the Congo was a place that Europeans felt was ripe for exploitation. Their use and abuse of people/resources was disgusting. There was a sense of mystery as they travelled into the heart of the Congo that these pilgrims could not comprehend. There was ultimately a price to pay for their greed. Weather men like Kurtz lost their mine, lost their soul or both is certainly a theme worth exploring.
