A lot of people think Dany has taken a turn down the wrong road. Despite having good intentions, she has often behaved irrational and cruel.
Some people point out that she only objects to slavery when it suits here. I wont go into that, but it is relevant here to keep it in mind.
There is the offer of the Tattered Prince wanting Pentos floating around. Not so good. And the issue of her having to abandon Meereen to be butchered if she wants to head west. She has to make a lot of sacrifices that conflict her supposed moral compass to get what she wants, and this brings me to subject -
The red priests are all slaves. They have their faces tattooed with flames. They buy slaves. Moqorro is a slave. And they seem to be Dany's main backers. I was wondering where anyone thought that might lead? Will she accept slavery if they are her faithful flame worshipping minions that fuel the fires she is going to burn half of Westeros on? Or will she try and bring down the red priests, too? Not likely. But it is an interesting conflict she is going to have to deal with...
