Discuss the deterioration of faustus ambition throughout the play?

Greed an pride get in the way of Faustus's original ambitions. As the play opens, the chorus tells the story of Faustus life to that point. Faustus has had a pretty normal life, growing up the same way others of his time did. However, Faustus has the advantage of being a brilliant scholar who can debate anyone under the table. Faustus is not happy with this little bit of success. He wants to be world renowned. He wants to be rich.

Faustus’s pride will not allow him to be happy with mediocrity. So, he begins studying magic and conjures a devil, leading to a deal over his soul with Lucifer. Faustus cannot be content with what God wants for him, and he turns to the devil for more. For these reasons, greed and pride are themes of the play.
