They were going to kill her, there is no point to the whole situation otherwise. Unless of course, the Others are actually, "good" people and were trying to help her, maybe the Losties have made a huge mistake, maybe the ones that are left are all the bad guys, and the good ones, have been taken. Perhaps there is nothing to be scared of, just fear of the unknown.
