Alice's missing vision?

I was re-reading New Moon and I was on Chapter 10, The Meadow, when a question popped in my head. I don't know if this question has been asked before, because it sounds familiar, but.....

Wouldn't Alice have seen Laurant's decision to kill Bella? I know the wolves came, but Laurant says he was hunting, so he would have immediately thought to kill her, leading Alice to her vision. I think that being killed by another vamp is much more horrible way to die than to jump off of a cliff, so Alice had a better chance of "accidently" seeing Bella's future.

This is really a question no one can know but you guys said you wanted more fan questions, and I thought it would be a good one to ponder about.

And another I just thought of...

If Jacob did imprint on Bella, would she choose him? It would seem so heartless if she didn't, but also if she did. I wouldn't be able to handle all the drama there.

Well, if Jacob imprinted on Bella than she wouldn't really have a choice but to choose him. I mean Bella asked him about that and he said that that kind of affection and need is just shared between them. If he imprinted on her than that would mean she is his PERFECT match, and in return he would be hers. Lol, don't know about the first question. I'm sure Stephenie has an answer for that one in an interview somewhere.
