Also, in the original stories, Robin actually was more like rob from the Church and give to the gentry. He was very friendly with the "right sort" of noblemen, he just really didn't like rich priests from the church. So we (in our modern age) have kind of perverted the idea of Robin Hood to fit our times but he never really was some kind of hero for the poor.
