I feel the narrator is saying that he found someone and took advantage of them to get what he needed (drugs/money for drugs). He used them so much that he watched them change from a person to basically nothing (a fly). He exploited their weaknesses "Pulled off your wings" and felt no remorse. The fact that the fly he's referencing "Like you never had wings" makes me think it was too easy for him to capture/manipulate the victim. Later in the song he seems to have found forgiveness for himself "I look at the cross...". As well as remorse about using the person and seeks forgiveness "Then I look at you" and "Give you the gun ... Blow me away).
He found his victim, exploited them for his needs, and left them with an addiction that he cannot pull them from.
