Okay I'm going to go against everyone else. I bet I'm going to look like a fool when I'm totaly wrong but, I think Juliette is upest and tierd of the B.S. that Ben has created. She said there are no leaders. That may be how they started out but, Ben has taken a position of power. She is also a doctor. A Vet yes but, she shares that with Jack. We don't know enough about what happened to the Other's to know for sure what she is being motivated by. There is a part of me that believes Juliette is trying to make changes to what she sees as a fawed and dangerous situation. The first time we see her she looks sad and appears to be working herself into a good mood. Even the music she's listening to "Down town." said she's unhappy. I think she will end up being an a good person. I hope I don't make a total idiot of myself.
