Therefore it would be without reason for a Catholic religious official to burn a Muslim at the stake because they are simply adhering to their own religion. Persecuted heretics were pursued by officials of their own established religion. Moreover, most medieval nations in Europe by 1200 after the end of the Moslem conquests in Iberia and Italy were very sympathetic to Islam based upon the financial and scientific advances Muslims brought with them.
Paganism is a totally different issue. They were burned for quote, being "Barbaric."
Putting all that aside, it's literally impossible to implement this idea into the game in the first place based upon the games coding.
