Melisandre's Manipulation of Jon Snow (ASOIAF Analysis)

In this video I want to dive a little deeper into what I talked about last time involving Melisandre, Jon Snow, and letters arriving at castle black during A Dance With Dragons. It turns out the pink letter is not the only one which influenced Jon Snow and was taken advantage of by Melisandre. Going back through Jon's chapters I can't help but wonder how much of this is a part of Mel's plans and how much of it is just her taking advantage of the chaos. I am also starting to wonder if she is fully aware and planning for Jon Snow to die.
