Pope took an oath to kill all Protestants/liberals...
This is what the pope not only swore to, but as a high Jesuit priest he enforced this dispicable jesuit oath:
...I furthermore promise and declare that I will, when opportunity present, make and wage relentless war, secretly or openly, against all heretics, Protestants and Liberals, as I am directed to do, to extirpate and exterminate them from the face of the whole earth; and that I will spare neither age, sex or condition; and that I will hang, waste, boil, flay, strangle and bury alive these infamous heretics, rip up the stomachs and wombs of their women and crush their infants' heads against the walls, in order to annihilate forever their execrable race. That when the same cannot be done openly, I will secretly use the poisoned cup, the strangulating cord, the steel of the poniard or the leaden bullet, regardless of the honor, rank, dignity, or authority of the person or persons, whatever may be their condition in life, either public or private, as I at any time may be directed so to do by any agent of the Pope or Superior of the Brotherhood of the Holy Faith, of the Society of Jesus...
