Who's the Protagonist??

When someone talks about a protagonist, what do you think of? For me, I think of one that does good to the story. In the short story, The Yellow Wallpaper, I think that the protagonist is Jane, also known as Charlotte Gilman. She is an innocent women with a "problem" known as hysteria. All her peers are telling her to sit around and do nothing for the rest of her life. The antagonists are the people all around Jane. They wont let her do anything, and they don't even care. They think that this is right. They don't even know that doing this will not heal her! It will just make her more crazy! Everyone is "locking" her up in a jail-like room. One with bars on the windows, torn wallpaper, and locked up doors, so she cannot escape. Yet, I still think that Jane Doe has a little bit of antagonist in her. Like, for example, when she thinks of John "fainting," she doesn't even care. She just still creeps around the room, stepping on and over top of him. That is why I think that Jane is both the protagonist and the antagonist in the story.

These are the links that helped me find out why Jane is the protagonist, and what it means:
