What might mccandless's motives have been for his behavior (par. 3) ?

Many have speculated over Chris McCandless's motives. Most agree that McCandless mostly wanted to start a new life and to experience things that would have been outside the realm of possibility growing up in the lower 48.

What motivated Chris McClandess's behavior was the desire he had to radically change his life by getting rid of materialism and American consumerism.

Explanation:

Chris treated everyone around him with a strict moral code. He was always ready to discuss and give strong answers to those who spoke one thing but lived another. The courage to live the fame he wanted, led Chris McCandless to look for another name to express who it was: Alex Supertramp.

Alex's goal was only one: to live radically what he believed, to plunge into wild nature, to lose himself and to find himself in it, until he did not know where one ends and the other begins. Before writing about it, he needed to live it, more than talk, he had to feel it and that meant changing his way of life radically. So many thought he was crazy because he was one of the few who left behind the hypocrisy of the words that everyone preaches and turned them into attitudes and actions.
