The bushranger Ned Kelly led a gang of criminals more than 100 years ago. He was first arrested when he was just 14 and then he went on to rob and kill people. But before his last infamous shootout, Ned Kelly wrote a letter to the world saying that none of it was his fault, that society was unfair and he had no alternative. So, can you really blame society for how your life turns out?
