Black and White Monsters Theory
Ok here it is then. Jacob and his enemy represent two opposing factions, one black, one white, as we see from their dress code. They are entities which can also manifest as clouds of smoke, one white and one black. Jacob is the white smoke, his enemy the black smoke. When Locke first encountered the monster is Season 1 we did not see what he saw, but he described what he saw as a bright white light. This was Jacob. Eko replied, "This is NOT what I saw". Eko saw the black smoke, Jacob's enemy.
The white smoke is fairly reclusive because he allows things to happen of their own accord. He is apathetic. The black smoke has a distinct goal - killing Jacob, and thus is frequently attempting to furthur that goal. Attempting to rationalise the monster's actions based on consistency is difficult, but view the monster as a selfish, power hungry entity, deciding who lives and dies only in so far as they will help with his plan, and he suddenly seems to fit the bill.
In season 5, Locke began time travelling. The monster's big plan was to convince someone to kill Jacob for him, and only a leader or former leader is allowed an audience with Jacob. He saw Ben to turn the wheel and be banished, so Locke would technically become leader, but the monster also told Richard to tell Locke specifically that he would have to die. He did this so that he would be able to take Locke's form. Once Ben and Locke's corpse returned he manifested as Locke, (we know he can manifest as dead people, he's done it before) along with all his memories (we know he can scan people's memories) so people would think Locke resurrected. When Ben summoned the monster with the drain, to be judged, Locke disappeared into the jungle and reappeared after. The monster did not turn up at this point because he was standing right there, as Locke. Instead 'Locke/monster' lead Ben to the temple where they became seperated. As soon as 'Locke' left Ben's sight out came the monster. The whole judging process was a ruse because the monster would never let Ben die, he is the most integral part of his plan. He made sure to manifest as Alex and tell Ben EXPLICITLY to do exactly what Locke tells him to. He then return to Locke form and helped Ben up.
The final part of the plan was to march directly up to Jacob, with Richard helpless but to allow it all to happen, even having to allow both Ben and 'Locke' to see Jacob because technically they both held the leader title. Finally he order Ben to kill Jacob and his master plan succeeded. --Integrated (User / Talk) 23:20, 15 May 2009 (UTC)
