What was the conversation between Marlow and his aunt before he left england ?

Marlow's aunt is lost in the colonial delusion that European powers is helping the natives that they subjugate. Marlow's aunt expresses her hope that he will aid in the civilization of savages during his service to the Company, “weaning those ignorant millions from their horrid ways.” Marlow knows that the Company only wishes to pillage and exploit the countries that they have interest in.
