I had some thoughts about Paul here (My critical thoughts about Paul), and I think a lot of the confusion, sectarianism, and contradictions in the NT is because people try so hard to reconcile the different Bible writers instead of accepting that they each wrote from their own viewpoint. Having this "There is only one way of thinking" mindset discounts that Paul thought differently from other apostles because of his background, and feeds the conformist structure of JWs and other fundamentalists.
Sorry, I went into college thesis mode there for a second, but the bottom line is: Yes, Paul did have a different way of looking at things, and his way of interpreting Christ formed it's own Pauline sect, which, by Paul's sheer force of zeal, became the default sect of Christianity that went mainstream.
