After all, one of them tried to kill him but he was saved by a member of Dharma. Instead, Jack doesn't operate (was that what he was brought back to do but refused his calling?) and Kate et al take him to the hostiles where he is cured, memory wiped, innocence lost. Which is what was supposed to happen because you can't change the future.
