So without any sort of "inspiration" what would make Paul change from a slayer to a Salesman? Not to mention the name change?
Well the name change, if it happened, does seem far more like conman or criminal. But remember, we simply do not have any information about Paul except that which has been filtered to show in his favor.
We either would have to conclude that Paul was a supreme conman or that perhaps he was led to change his mind..(and heart?)
Why? Why do you always try to make things an either or situation? He could have been delusional, a madman, a fanatic, a figment of Luke's imagination, or even a very small bit player who just happens to be known because some of HIS writings did not get destroyed while the writings of others were lost.
