He was excommunicated for his views, he was facing death at the hands of the Catholic hierarchy. He wasn't a priest anymore. He got married (a holy estate), stayed married to the same woman, had children and made some money. Sounds like a conservative.
Facing death? What Inquisitional Tribunal did he face? What death did he face? Answer: none. He lived his life in wealth and privilege and died a natural death, untried and unmolested by the Church. The only death he faced was his natural one. Not affected by the Church whatsoever.
He turned out to be a pawn in the game of international politics, but a well paid one. Conservative? More like a man whose enterprise was bought out by bigger forces because they could use him and his enterprise to their better use.
