Just because someone claims The Blessed Mother told them something, doesn't make it true. Far too many seers and visionaries have been exploiting Catholics' devotion to Mary in this fashion for entirely too long. If "the chastisement" has begun, it seems to be a very selective one which is contrary to every divine punishment in Scripture.
Perhaps you would, but if Scripture is any guide to chastisements sent by God and that seems to be a fair assumption, then they simply don't work that way. You see any fire 'n brimstone soaking downtown Berlin? Has Cardinal Marx suddenly coming down a plague of loathesome boils? ;-)
