Mephistopheles: Although Mephistopheles appears to Faustus as a devil — a worker for Satan — critics 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. Farnham explains, "Nor does Mephistophiles first appear to Faustus as a devil who walks up and down in earth to tempt and corrupt any man encountered. He appears because he senses in Faustus’ magical summons that Faustus is already corrupt, that indeed he is already 'in danger to be damned'."[4]
Mephistopheles is already trapped in his own hell by serving the Devil. He warns Faustus of the choice he is making by "selling his soul" to the Devil: "Mephistophilis, an agent of Lucifer, appears and at first advises Faust not to forgo the promise of heaven to pursue his goals”. Farnham adds to his theory, “…[Faustus] enters an ever-present private hell like that of Mephistophiles”
