If curiosity had killed a cat, that cat is Faustus. It's a story of a well learned doctor turning into an evil person, the story of theology specialist who became an obedient of Lucifer. How does the story proceeds and how comes the tragic end of the great Doctor? requires learning the story once atleast.
Regarding Marlow, it is truly said, if there was not any Marlow there wouldn't have been any Shakespeare.
Thank you for reading.
