Jack decided he didn’t want to svae Ben, so instead Kate & Sawyer took Ben to the others, where Richard says “He’ll forget this ever happened, and that, his innocence will be gone”. NO!!!! I have never agree with the theory that we can’t change the past. If time travel is possible, then we must be able to change the past. Oh yeah and how is Sayid that bad of a shot? He should have easily been able to kill Ben.
