JACOB MIB COMPARISON

Now that the focal point of Season 6 is on the mystery men, Jacob and MIB, let's chart some traits to see how they compare:

HUMAN BODY:
Jacob: Yes, he was stabbed with blood and burned to ash in fire (which was not crematory hot so could have been an illusion)
MIB: Yes, he said he had a body, and form as MIB

GHOST:
Jacob: Yes, after stabbing appearing on the island
MIB: Yes, as Flocke with no blood when stabbed by Sayid

ABILITY TO TRANSFORM:
Jacob: Yes, into a ghost
MIB: Yes, into Smokey and Flocke

ABLE TO LEAVE THE ISLAND:
Jacob: Yes, touched candidates/O6
MIB: Unknown

VIOLENCE:
Jacob: Yes, beat up Richard
MIB: Yes

MURDER/KILLING:
Jacob: Not directly
MIB: Yes, from pilot to temple Others

MIND READER:
Jacob: Unknown, but had lighthouse ability to get information to manipulate
MIB: Possible, as Smokey to mind scan to get information to manipulate

ABILITY TO GIVE LIFE:
Jacob: Yes, to Locke after his fall
MIB: Yes, to Richard who appeared "dead" in Black Rock hole

PURPOSE:
Jacob: Secondary sources: protector or guardian of the Island
MIB: Secondary sources: Island "security system"

SELF VIEW:
Jacob: "Replaceable"
MIB: "Trapped"

ON RIVAL:
Jacob: MIB "is wrong" on his view of humanity
MIB: Jacob "took my body, my humanity."

POWERS:
Jacob: To bring people to the island; to grant eternal life (to Richard); to "steal bodies" (MIB)
MIB: To shape shift forms

HOMES:
Jacob: Cabin in the woods surrounded by ash, and foot of Tawaret statue
MIB: Beach cave, and under Temple walls.

The last points got me to thinking that much of the island decor may be the ability of the island supernatural residents to create them by shaping matter into physical objects. It is then possible to believe that MIB used the collective memories of the Egyptian people brought to the island to create the Smoke Monster (Apep) from Egyptian mythology. And with the popping up of unknown new children this season in Other-like old clothing, a new theory emerges:

What if these (supernatural) children are playing "make-believe" with other people's memories, fears, and emotions?
