Mephistophilis

The one part from the reading that really sticks out to me is the character Mephistophilis.  He sticks out to me because he is a complex character.  At times he seems like he is a good devil (if that is even possible), yet he is still a devil and servant to Lucifer.  Sometimes I wonder if he regrets his decision to go against God.  This character works to achieve this effect by being perceived one way, yet acting another.  The reader expects him to act like a normal devil and try to persuade Faustus to go against God and come to hell, yet it seems like he is doing the opposite and warning Faustus about what happens in hell and how even when you are not technically in hell, you are still in a hellish state.  It will be interesting to see how Mephistophilis changes throughout the play.  Will he keep warning Faustus about what hell is like or will he change his mind and encourage Faustus to come to hell?
