You're all right about this. I see a lot of comments on other boards about her and I think to myself, didn't any of these people watch the previous seasons? Daenerys has shown in almost every season that she can make some pretty ruthless decisions. She's not all there in the head. If it wasn't for her advisers along the way talking her out of some things, she would have done some pretty horrific things in the show already. Now she doesn't have any advisers to talk her off the ledge and look what happens.
