Jacob told Jack, Hurley, Kate, and Sawyer that he chose people to bring to the Island who were like him: alone and flawed.
However, if we are assuming that Jacob's touch is what brings people to the Island, and that he can reverse his decision about Candidates whenever he chooses (like Kate when she became a mother)... why the HELL did he take Sayid back?!?!?
Sayid, who had finally found the ONE THING he wanted all along... Nadia! He WASN'T alone and flawed anymore... he had given up his past life to finally, finally rest and be with the one thing that had driven him all along. He no longer fit Jacob's reasons for choosing the Candidates, so why wasn't his name crossed off the wall?
WORSE, if we are assuming his touch somehow caused Nadia to be hit by that car...
JACOB IS THE BIGGEST LYING, MANIPULATIVE ASSHAT ON THE FACE OF THE EARTH.
