Scene VI - X

Why does Faustus want to raise the dead so badly? He obviously doesn't know how to yet, otherwise he wouldn't have needed to use the demons as Alexander the Great and so on. Does he want to unleash a deadly army on the world? Does he want to bring God back to life or Jesus? Does he want to become the new God? What ishis reasoning for even wanting to be a part of black magic? He knows all about God and now wants to know all about the Devil? Was his whole life spent working for this moment? He wanted to be a teacher, a healer, he wanted to know earthly rules, and wanted to know all about God and the Devil, so he could become more powerful than they are?? But he is failing because the Devil definitely  has Faustus twisted around his finger...
