I think Chris McCandless was a hero for many reasons.
First of all, he inspired adventurers across the world with his trip to Alaska. They saw him leave all he had to try to accomplish his dream and wanted to do the same. Another reason I think Chris is a hero is he helped turn an alcoholic’s life around. Chris met the guy when he was very lonely, living alone. But they formed a friendship so strong that the man wanted to adopt Chris because he felt like his son to him.
Also, Chris cared for the less fortunate. His family was rich, but he didn’t think he was better than everyone else because of it. He would skip big parties to go and give food to the homeless. Lastly, before starting his adventure, he donated all his savings ( $25,000) to OXFAM. I think all these thing make Chris McCandless a hero.
