It's beginning to feel like blaming the victims.
I guess you can argue that's exactly what they've set up. The "victims" the Oceanic survivors, crash and go through hell. Then 6 of them get back only to go through more hell and ultimately go back to the island.
In the process of being back on the island, they set events in motion (Ben's shooting, and the subsquent "taking over" by the others) that helps create one of the guys that's mostly responsible for a lot of the hell they went through.
And it's beginning to look more and more to me that we're ulitmately going to discover that something they did "back in time" is what led to their plane crash.
Jeez, talk about getting stuck in an infinite time loop.
