Wuthering Heights paper

For my English 251 class, I have to write a paper on "Wuthering Heights." I decided that my argument will be that the death of Catherine (the first) is actually a beneficial event for every main character in the story. I also have a basic outline of the paper with an introduction, a body listing reasons that Catherine's death is a good thing for the characters of Edgar and Isabella Linton, young Cathy, Hareton, Heathcliff, and even herself, and then a conclusion. I plan on posting bits and pieces of my paper as I write them, so if you have any opinions, feel free to comment.
