This will largely depend on the opinion of the individual reader as to whether or not McCandless' choice was the "right" one. I couldn't help but think, as I was reading of his death by starvation in the Alaskan wilderness, that he was a complete fool. His choice was not suicide, his choice was to live as one with nature like a modern day Jack London, yet he walked off into the Alaskan winter almost completely unprepared in either clothing or survival gear. He didn't want to die, but he made choices where it was much more likely that was going to happen.
I was even a little resentful that a book and a movie had been made of his life, as though his choice was somehow admirable or even worthy of study. I suppose his choice was unique, and maybe he was a great person individually or intellectually. So much more the waste.
