Excellent point Don Al.

I have written extensively about what role Tom Hagen would have played in GFIII, including the idea that he would have never allowed Mike to get tricked by the Church and the Immobiliare people. I do not think he would have approved of Vincent at all, however, had Mike not been screwed by the Vatican there would have been no need for all the bloodshed at the end, and thus no need to elevate Vincent to be the Don.
