Yes, much like the Protestant Elizabeth I burned Catholics-- and hunted down priests and those who hid them and had them hanged and quartered, burned down Catholic churches and monasteries and seized their lands and their cathedrals. Such was the tenor of the times.
When the Mother Church excommunicated Elizabeth in 1570, it was basically telling their faithful it didn’t have a problem with her getting whacked.
Liz’s religious tolerance grew strained as the fatwah intensified and, yeah, she put what she perceived to be traitors to death, often drawing and quartering, privy parts cut off, etc.
Including the principal character of this thread, Mary ‘Queen of Scots.’
But from her Pop’s reign to Charles II, about 300 Catholics were executed, most by beheading and hanging. Mary killed that many reformist/Lutheran ‘heretics’ in her reign alone, most by burning.
