Well, it's based on the demon that made a deal with Faust, that's sorta the origin of the Deal with the Devil trope (I believe).

If it helps, the effect I'd give it would be something like it being attracted to make deals only or mostly with those who are already to some extent corrupted/at risk of being corrupted (since some interpretations "claim that he does not search for men to corrupt, but comes to serve and ultimately collect the souls of those who are already damned.")
