In before Dany doesn't end up a villain in the books. (not a "Mad King Aerys II" type villain anyway, she'll kill a lot of people, and there will be a lot of discourse about it)
By this I mean to say that the author won't write her character or the perspective about her character to meaningfully change. So if you don't think she's a villain by the end of book 5, you won't think she's a villain by the end of book 7.
