Into the Wild

In the book Into the Wild Chris McCandless decides that he is sick of his normal everyday conformist life and wants a change. He decides to have an adventure crossing the western coast of the United States in search of finding self enlightenment. Since this was a true story and was only dictated by Jon Krakauer I would hve any plot question for him. If I did meet Krakauer I would hae a couple of choose questions of how he set up the events.
If I were to meet Krakauer in a coffee shop I would like to ask him a few questions. I would like to know if he believed that McCandless was mentally ill or if he believed he was wiser than us all. I would like to know if Krakauer believed that it was justifiable that he leaved his family without a word of notice. One of my biggest question would have been that, why did he believe that McCandless always tried to push himself to the edge to his utter demise?
Krakauer would have insight on the inner psychi of McCandless and would be able to answer the questions I would inquire. From inteviews I have read I realized how intelligent Krakauer is and how he has the ability to give his opinions about his book Into the Wild.
