Weird Characters

One thing can be noticed when reading the book which is there is no villain in McCandless' story but himself. Every person that he have encountered in his journey were a friend; never a foe. The German couple, Jan Burres, Ronald Franz and many others. The have provided aid help and shelter for him. I can't seem to remember that I've came across any character that wasn't nice to him. They may have liked him or his personality and charisma, or maybe he was a good listener because people always talk to him in the book, or even they might feel sorry for him because of what he's going through at the time. Is life really this beautiful? Who knows?
