How does Chris McCandless's family description about him differ from other?

There are generally two major views of Chris McCandless: one holds that he was a progressive thinker who wanted to relive the adventures of naturalists and transcendentalists in a modern age, improving his mind and becoming a classic American Individualist; the other holds that he was a pampered rich kid who never took the time to prepare for the hardships of the wilderness, and his death was the result of simple stupidity.
