Why Jack wants to go back to the island after his rescue?!
Question: Well, no one knows at this point. We can only assume that he has realized that they were meant to stay on the island, and when they left the island it screwed with the time/space thing, and everything is all out of whack. I am pretty sure that there is also some threat to the ones who remained on the island, and that the "Oceanic 6" need to return to the island to set things right in the universe, and ensure the safety of the remaining survivors. They have definitely cleared the question up that we have been wondering about for quite a while. That the island has special properties that affect "time". That is why the island was impossible to find. When the hatch blew up it caused a reaction in the atmosphere that allowed them to be detected briefly (by the ones who are working for Penelope). Jack is not the only one who has indicated that the people on the island need them to return. Charlie (who is dead) appeared to Hurley back in America and told Hurley that "they need you."

To pal out with Gilligan.
guilt - I think he's sorry he left the other Oceanic 815 survivors behind
:o)
Probably because of post traumatic stress.
You know the cases about SOME of the Vietnam war survivors, who after coming back to their normal lives, are disturbed... and sometimes they LONG for the action of war once again.
I think its the same with Jack. He longs to be back on the island he was stranded at.
