Juliet is a damn asshole. She is talking about morals, it doesnt matter what they did as they arent anywhere near what they did. It is her they are dealing with.

When Sawyer and Sayide need to they protect their people, and she aint there people and her blood needs to be on their hand.

SO sick of these people (The Others) acting like they are God, can do what they please and throw other peoples actions in their faces.
