''I heard his voice! He was begging. Mom, Help me!'' Chris failed to notify anybody of his whereabouts, if he hadn't had done this he could've been saved.
Chris can hunt and survive for a while.
Chris gave up a job offer that would pay well and the boss really wants him to keep working there but he declines the job anyway. This tells me Chris was really committed to going off into the wild, and he took it very seriously.
Chris didn't bring the needed materials.
''He resisted instruction of any kind'' Chris was a kid who didn't want anyone to tell him what to do. He needed to figure it out himself. This stubborness could have caused him to not think straight
Chris eventually dying on the bus.
''Overjoyed, the proud hunter took a photograph of himself kneeling over his trophy.'' Chris can clearly live on his own, he isn't just some random kid.
''Deemed essential by many Alaskans: a large caliber rifle, map and compass,an ax.'' This shows that McCandless came unprepared, and that could be a reason for his death.
''The only way he cared to tackle a challenge was head on, right now.'' This tells me Chris may have been to arrogant to think he cant die in the wild.
