Hell & Manipulation

What if the Pharasees in Jesus' day taught the idea of hell (borrowing it from other religions - Mesopotamian, Egyptian, Zoroastrian and Greek) in order to manipulate people to be good, so that the Messiah could come?  What if Christians started to do the same thing, causing a seperation between people who go to heaven and people who go to hell?  What if Jesus is all about breaking down this seperation, by hanging out with the 'sinful' people and turning the idea of hell onto the religious establishment?  What if Jesus was only ever warning religious people about hell?
