In all seriousness, i despise what they did to Thay. It was another nail in the coffin for the 4e Realms for me. So, since i took the nation in another direction in my home Realms and 5e needs a frigging miracle to get me interested in canon Thay again they might as well turn it into a theocracy of fanatic pyromaniacs, at least then i can laugh while reading about it and picturing red robed warrior priests setting the f*****g zoophiliac b*****s of Rashemen and their drunk toy boys on fire.
Fear not, though, for Szass Tam's actions lately seem to indicate he'd be overstretching his limits soon. Building Dread Rings in the Sword Coast where many major cities are well prepared to crush any potential threats? A particularly unwise move.
