i guess neither of them are important. but some characters are a real pain in the ass. There are few well behaved characters too, they would do as the author wants, you know, like the red riding hood will meet the wolf. Meeting the wolf becomes her characteristics. But then there are some who rebel. Those i call the "rouge characters".
I quote Harold Pinter to describe them to you: “The author’s position is an odd one. In a sense he is not welcomed by the characters. The characters resist him, they are not easy to live with, they are impossible to define. You certainly can’t dictate to them… To a certain extent you play a never-ending game with them, cat and mouse, blind man’s buff, hide and seek. But finally you find that you have people of flesh and blood on your hands, people with will and an individual sensibility of their own, made out of component parts you are unable to change, manipulate or distort.”
i guess i should indeed write a hub about these rascals.
