Faustus discusses raising the dead and all the political actions he is going to do once he gets power. Why do you think he does not do these things?

In context, we can almost say that once Faustus has achieved his goal, he simply loses interest. On the other hand, it is obvious that Faustus begins to feel remorse.... that he thinks about redemption, and then he rethinks redemption believing it is lost to him. Faust is torn between what he desired and attained, and what those things will cost him in the long run.... for eternity.
