How can Desmond have caused the crash? Sure he missed an entry on the crash day. But that only happened because he chose THAT day to follow Kelvin. It was a random move, right?

So if this plane is full of 'special people', many of whom seemingly 'chosen' to fulfill some destiny, with all of their pasts interwoven as per their backstories...how could their 'pre-destined' crash be left to the random possibility that Desmond would go out on that day?

Desmond cant be right...something/one else did it. You know how the printout reads numbers entered and 'accepted'? Accepted by whom?

Maybe on that day the numbers were 'not-accepted' by whomever wanted that crash to happen and Desmond had nothing to do with it.
