Are they Dead ?????

Ok so I am not sure if what I am writing is gonna be posted as a question or theorie…. I dont know if anyone has wrote this before, if you did I apologize….. When Locke got pushed out of the window by his father, Jacob came up and touched him….. To me Locke looked as if he were DEAD! Also when Ricardus was in the Black Rock chained up he also looked DEAD to me. Then the MIB came down and touched him and he looked like he was rivived same as Locke when Jacob touched him. Now am I just seeing things or did they look dead to everyone else too…. Thats where you come in…. I need help to know if what I am sayin is true… and if it is then that means they both have the power to bring back the life to who they touch…. I was thinking it can only be a “candidate” BUT Ricardus is not one or is he?????? Maybe he is the one who is supposed to be the MIB candidate not Locke…. I see Locke as just a shell (a body) for the MIB to use till he gets free than take over Ricardus for his body which he can never die “live forever” in his words. In the last episode he said he wanted to take him up on his offer if it still stood….. I think our beloved Ricardus might be going to the otherside……. He wants his wife, he has no idea what to do now that Jacob is dead whats left???? I am not sure if I am right or even a little but if u can comment and let me know what you think it would be much appreciated……. thanks
