I don't like LOST's version of time travel. It just doesn't make sense to me that a time traveler can't change the outcome of a situation. Anything different from the original event would change the outcome. It would cause a "ripple". I know I am getting this from the many time-traveling movies I have watched, but it makes sense. (Frequency and The Butterfly Effect are excellent example of how interfering with fate can change things drastically).
This whole "if he helped her now, he has always helped her, has me so confused, I can't get my mind around it. There had to be an ORIGINAL event. One that did not have time travelers witnessing it. So, Sawyer sees two Other's getting ready to shoot Amy, the original event, had Amy shot and dead. (Her husband was killed, and they were getting ready to shoot her execution style). So, Sawyer comes in and saves her, all that means is he now has to ALWAYS save her, when he finds himself in 1974 and she is getting ready to push up daisies. It still doesn't make sense that by Sawyer saving her, he did nothing to change the future. I just don't get that. Original '74, Amy is dead, Horace can't divorce his wife, and marry Amy and have a child, because SAWYER WASN'T ALWAYS THERE.
Who else shares my frustration with this? Am I missing something? I think the Losties can change the outcome of what happened in the past, and will.
