remember when richard went to visit locke as a child b/c locke basically told richard to? remember the picture on the wall that richard asks locke if he drew it? the one where the smoke monster appears to be coming out of lockes head? thats b/c its forshadowing that locke will indeed become the smoke moster or that he will be possesed by the monster. also the reason why richard was upset with locke choosing the knife is because richard already knew at that point that locke picking the knife meant that jacob was going to be killed by the knife. and i believe that if locke choose the book of laws that all the bad things wouldnt have happened thus jacob not being stabbed and the rules wouldnt have changed!!! let me know what you all think!!! thanks!
