Is Juliet good or evil?

I think she's pure evil, and we'll be mislead for a few more episodes until we finally realize she's just a part of the Others' larger plan and betrays the trust she's trying to build.

I think that in the end she will be discovered as a good one.

I think she is genuinly good, she's the only one from the others that is more open to dialogue with Jack and his group whenever possible and she has a very tender, friendly way of approaching just about any person. Not sure if she wants to project the project though, but one can see it is in crisis itself and she's clearly worried about it.

I've gotta say I'm not so sure about her. Something about her eyes, and she's never been too nice to Sawyer. Also, she didn't get very mad when Ben left her to die with Jack (or at least we didn't see her get too mad).
