I have heard all sort of things about Jack being the next in line after Jacob, I have major issues with this. It seems to me that every choice he has made on the island about the island have been wrong, from trusting Ben as Henry Gale, to pushing the button, fixing Ben, not fixing Young Ben, detoning the bomb. The only thing he has got right is not poisoning Sayid but if that is to save the island it again is the wrong choice. Someone please give me a reason to think he is the right choice!!
