So I was reading about Jan Hus recently and found out that even though he was promised safe-passage by Sigismund of Hungary, was arrested, tried and executed. So what if the same happened to John Luther at the Diet of Worms? What would the reaction be, both in Germany and throughout Europe? Would the Protestant movement be strangled in the cradle or would Luther become it's first Martyr? Would all of Europe remain Catholic or was the break inevitable?
