I'm not totally sure, but to me, it sounds as though he is describing someone who is selling their soul to the devil.
The song title would certainly tie in with this, it is based on the phrase "Better to reign in hell, than serve in heaven", which is spoken by lucfer after he is cast down from heaven in "Paradise Lost" by 'John Milton'. This makes sense, because the result of him selling his soul will be that he goes to hell.
