So why did Rosalie want to kill Bella?

In the canon there is this piece of 'fan-fiction' called "Midnight Sun," and it takes Twilight and tells it from Edward's perspective.

It is a treasure-trove of Twiverse information. I would call it essential reading for all fan-fiction author(esse)s, and you can take my word on that to the bank because I nevah! descend to hyperbole!

Evah!

*ahem* Hanywey.

Anyway, in the outfall from "Phenomenon" chapter (when Edward impossibly (for a human) saves Bella from the van) when the Cullens have the family meeting to determine what to do now, Jasper is bound and determined to murder Bella, and ...

And Rosalie not only "supports" Jasper, but if he welches on his promise, then she more than willing to murder Bella in her sleep. And what is the reasons she gives for her cold-blooded plan?

1. She wants to finish high school.


2. And they've only just moved (back) to Forks, and doesn't want to be inconvenienced with another move so soon.

Now, I'm all for accepting statements at face value, but I think there's something (much) deeper going on with Rosalie's sudden and poorly explained hatred of this newcomer and threat to the happy vampire family that Rosalie so happens to be co-located with.

Why?

Well, let's examine her given reasons:

1. She wants to finish high school?
   
   Rosalie has existed for more than 80 years, and she has been in and out of high school AND college probably more than 8 times (she starts high school by transferring in to at the very lowest 10th grade). So she's upset that Bella is going to break up her already broken record (*ahem* Emmett, remember those students you killed by accident 35 years ago?)?
   
   Um, no.


2. She's only just moved into Forks, WA and she wants to stay?
   
   Okay. Forks, WA? Been there? I've lived there. Not there, specifically, but smalltown USA (Moodus, CT, if you must know). A town of comparable size and industry. Do you know what people say when you ask where they come from? If they come from smalltown USA, they either say nothing, or they say "you haven't heard of it, but it's near [some city that it's nowhere near to because it's so far in the styx]," or they say "I come from smalltown, USA." The emphasis is on the come from because they left that life behind.
   
   Okay. You're from smalltown. You love smalltown. You've been to Town once and hated it. You are going to rip off my face for my insults.
   
   But one things you aren't ... is Rosalie. She came from Town: Rochester, NY. You know, where they have cars, right? And stores that aren't run by your neighbor and aren't the only stores in town? And they have more people than either cows or trees or both?
   
   Rosalie in Forks, WA? Sure, out of necessity. Rosalie LIKING Forks, WA? Maybe if you replace the town "Forks, WA" with "NYC" we could have a conversation where we both weren't laughing at the sheer lunacy of it, but Forks, WA?
   
   Um, no.

Offing a girl for either or both reasons Rosalie gives? Possible, plausible, even, I suppose, but not the reasons Rosalie wants to off this girl.

What is the real reason Rosalie wants to kill this stupid little doe-eyed human who's seen too much for her own good? Yes, Bella is a threat to the Cullens, and therefor Rosalie's comfort (you DO NOT mess with what is Rosalie's), and both are good enough for most people to accept that Rosalie would be more than happy to off Bella. After all, it was good enough for Jasper. She's broken the Rule, she dies. End of story.

But for Rosalie, it goes much, much deeper than that.

Why?

She's built up this little castle around herself. She has her Cullen family and her Emmett, even, lulled into this sense of security about her: "Oh, that's just Rosalie, the dumb, bitchy blond, so we can ignore her."

If Edward gets too inquisitive with her mind, she can think about brushing her hair, and he tunes her right out. She is, after all, his oldest sister, and knows how to play Edward like a fiddle. Just because he can read minds does not mean he sees into the soul. He 'knows' Rosalie, so he probes no further. Edward is no threat to Rosalie.

If Emmett gets too "Hey, babe, what's happening? Is something bothering you?" She knows exactly what to do. Emmett is all surface (c.f.: Midnight Sun), what he believes, he says, and he sees everything simply. Rosalie's unhappy? What's up with that?

Nothing, after she takes him on a little ride, because now he's floating on bliss, and Rosalie looks happy, so she must be happy.

The other family members are less of an issue that either Edward or Emmett. There are just too many people in that family with too many issues for her to become the focus of attention.

Rosalie may have wanted, and got, the admiration of every man at the ball when she was human, but here, as a vampire, she's ignored, and that exactly how she wants it. If she's left alone, she can't get hurt again.

But then along comes that little meddling human, and she sees right through Edward. In fact, Rosalie was sure Edward was so asexual, he wasn't even interested in men ... I mean, he and Carlisle had plenty of chances for something to happen, but zilch came out of that. And if Edward wasn't interested in Rosalie, then Edward wasn't interested in anybody.

But Bella just blinks her big brown eyes at Edward and he turns into playdough in her fragile little human hands, and, Edward, being Edward, has never shared anything with anybody. WHICH IS FINE WITH ROSALIE, because Edward's a big jerk anyway, rejecting Rosalie like he did.

Jerk.

But he told that human everything and I mean everything! I mean, not even Mommy Esmé has dragged so many words out of him in the last 50 years! And the little human did it just by looking at him.

And he can't read her mind. She's a complete void to him. Inscrutable.

So what if her power is something more than her blandness and blankness.

What if she can see into the soul, like that foolish boy Edward cannot?

And if she looks at me? And what if she sees what she sees of my soul.

I know what she'll see, because I recoil from it every second that I have a quiet moment, alone and to myself. That's why I'm always with Emmett or somebody, even if its that cad Edward.

I've never had to directly confront myself, but if that little human looks at me, and blinks her big doe eyes, and says: "Rosalie ..." with her chin quivering like that and with tears leaking out of her eyes, as they do not leak out of mine?

If she sees me for what I really am, she'll ... she'll ...

She'll know. And she'll pity me. And she'll tell the Cullens. And then they'll know.

She must die. Right now. She knows too much already. But she can't know me, because that'll mean that I'll have to know me, and that cannot ever happen.

I've got this comfortable existence with family members I can push around and manage, I can't have this whole façade threatened.

Bella Swan must die.

And if Jasper doesn't man up and do it because he's wrapped around Alice's ... fingers, then I'll do the job myself.
