you have to realize the mentality of the papal church in the middle ages.
through some sick twisted way they claim inheritance to the sceptor of rome and feel it is the holy fathers duty to "lead" the backslidin christian nations back under the holy fathers "wings". thats why the pope will try to take out any agent or character of yours that he can with the hope that somehow either his faction or one of his cronies can claim your lands.
