to kill those deemed insufficiently loyal to Rome
"Loyola's mandate was that the end justified the means, and any means of restoring Vatican domination was acceptable. The mission of the Jesuits was the extermination of all heresy and all heretics.

This murderous justification apparently became their creed."
