Red John = Reede Smith....

The name  "Reede" translates to " Red one " in Old English...So his name is really " Red Smith "....

Also...The RJ alias " Roy Taliaferro " translates to "King Smith "....

Further ..... The name " Smith " itself is from the Old English word "smitan", which means " to strike "....

So Reede Smith = "The Red One Who Strikes" with the alias " The King who strikes "

Read
the poem "Tyger Tyger " by William Blake...It describes a mythical
godlike "Smith " who creates a fearsome, deadly creature in a furnace
that exists either in heaven or hell....He uses a hammer and anvil to
imbue this "dread" creature with terror and death...

Blake isn't
talking about a real tiger of course... which is why he misspells it "
Tyger "...The Tyger symbolizes the evil that exists in this world ...And
Blake asks how the same smith that created the Tyger could create a
person like Jesus of Nazareth (the lamb )

Red John also thinks of himself as a godlike ( Smith-Reede Smith ) who can create an evil entity of great power....and he has created the  Tyger-Tyger Organization

Reede Smith may not be Red John but he will forever be the RED JOHN SMILEY!!!!!!! :-)

The only two suspects from Jane's list to appear in the episode Red John are the actors for Bertram and Smith. 

Now unless they will hide the actor who plays Red John's name from the credits, then it could be basically anyone else. 

But I read somewhere that the actor who plays Red John has stated that he thought he was a Red Herring and that he was in fact on the list. 

Personally I really really hope he isn't on the list because it will be pretty anti-climactic.

Now if it is either Smith or Bertram, I'd opt for Smith simply for the reason that Bertram could not be Red John after the stunt that Jane pulled in Strawberries and Cream otherwise Bertram having concerted with his accomplice would not send his killer into the trap. Especially not to the room number he himself was given. 

Smith is also, I think, a poor choice for Red John. There is no reason to exclude him though other that the fact the he is not old enough to have been the person drawing the smiley face after the killings at the visualize barn in 1988 (he would've been 12). But he is still more likely than Bertram to me.

I think it is reede smith since if I remember correctly the creator of the show said the audience will probably be disappointed with who red john is or something like that

i think red john is reede smith beacuse in the last episode he say he Afraid of high places same thig of red john
