Red john is janes stepbrother. after he left his father his father had another child in the hope it would be like jane but after years of being compared to his brother he also left . The smilie face is his clown makeup from the carnival where he and Jane worked but while Jane was a headline he was the clown . That's why he knows about janes past and is obsessed by him . Then years later he is publicly ridiculed by Jane the brother he was always told he wasn't as good as . He then kills janes family and starts a game with him. He has cosmetic surgery to change his appearance which is from the episode where bob asked a known red john accomplice if he recognises him then is relieved and kills him .

Tyger, Tyger,

I am sure ya'll read the poem?  I stated in an older theory that Partridge was a pawn and it was confirmed on the first episode.  I believe RJ had Partridge record the message Jane received prior to sacrificing him.  Due to the fact that the message was not a message that returned any answers jane asked about, it just stated a message.  So I believe Partridge was in fact a disciple of RJ and maybe CBI Ron is too, since I saw the picture of him on the phone when Patrick got the call. 
Anyway, to the tyger tyger poem, I believe that the meaning behind it is what I have stated before that Bret Stiles is Bob Kirklands father and Kirkland is responsible for the killings and is the true Red John.  The poem insinuates that the tiger is a resourceful beast and very dangerous along with a passion for killing. how the tiger is so beautiful of a creature can be so deadly (symmetry).  The poem goes on to say "In what distant deeps of skies, burnt the fire of thine eyes?"  (What made him like this?)  "And what shoulder, and what art, could twist the sinews of thy heart?" (I believe it is saying what life changing occurrence led you to these acts of heartless crimes)  The next verse I am surmising is based on creativity and creativity back in 1794 when Blake wrote this poem, there wasn't much outside of a Blacksmith. So it goes on to say "What the hammer? what the chain? in what furnace was thy brain? What the anvil? what dread grasp, dare its deadly terrors clasp?"  (Think of creating a sword, a Blacksmith would hammer it and furnace it and shine it up bright, yet what he just created was not only a work of beauty but a tool of death, again symmetry)  It is a metaphor.
ok, the last part which brings me to my idea of the father and the son theory is..."When the stars threw down their spears and watered heaven with their tears, did he smile his work to see? Did who made the Lamb make thee?"  (ok I know Im getting deep here but once the beast is unleashed and the damage done, did the father smile at what was created?  I believe blake was referring to when God made man and the Lamb, Jesus.  (the sacrificial lamb)  "Did who made the Lamb make thee?"  I think the question here is, is the beast a direct result of the fathers personality, is Stiles responsible for the way Kirkland (RJ) is. Did Stiles somehow kill Kirklands mother? Or was Kirkland made to do Stiles bidding?  The lamb being the innocence of a child who turned into the tiger, the apple doesn't fall far from the tree.  We have seen the people associated with RJ take their own lives, that is some heavy shit!  Who other than Stiles could do that??  I know what your gonna say, Patrick could.  I guess but for what purpose?  Lets just say his wife was going to leave him and he killed her like some other theories ponder, and he made up the whole RJ thing.  So why keep going?  He got away with it.  I think the problem with RJ became an issue when Patrick started to gain momentum and it is a pride thing with RJ, a game so to speak.  Who is better at this game?  Anyway, I will get back to work now and continue to believe my theory.  I hope you enjoyed my twisted mind for a while.  thanks.  I enjoy reading all your theories too.

As of right now I don't lean toward any of the 7 being redjohn. All i know that each of them has at least one reason as to why they're on the list and jane would have his reasons to put them on the list so i trust jane's reasoning. And I do believe that bruno heller is smarter than all of us here, he's had 6 seasons to plan everything. We could be guessing the right things or just wasting our time here. So I'd prefer to get whatever clues I can get but allow myself to go along with the flow and have fun with it.

What I do want to say is that do you guys realise how many times its been repeated that redjohn is always 'One step ahead of jane'. But what if... what if jane is actually one step ahead. What if he knows that Bob Kirkland has a relation to redjohn thus explaining why he 'allowed' bob to break an entry to the rooftop place and then when bob passed the information to redjohn, redjohn could follow jane's thoughts and come up with the list of 7 suspects before jane did. Or at least before jane showed lisbon the list. But in truth, jane actually has a strong hunch who redjohn is out of the 7. And he told lisbon because he knows lisbon would want to tell the rest of the team. He wanted lisbon to act the way she did and bug the phones for whatever reason that only jane knows. However he probably thought he could catch up with lisbon before redjohn does anything to her. Clearly he got that part wrong. 

Maybe jane is doing one of his things where he pretends he doesn't know anything, but in truth he's playing the role of the mastermind and trapping redjohn.

Bob Kirkland had the resources. He has the power. He had Jane's files and he had access to the case. Eventhough it is too obvious, I can't disagree with this theory of Bob being Red John.
 By the way, I think I have a theory about why Brett Patridge was killed first in season 6. Maybe because the writers could make a sinister motive behind his death and he was the most accused person on this Website!!!!!

Just some questions :1, How is it possible for Reede Smith to be on Jane`s list, when we all know that Red John is a slim person (we`ve all seen him in the last episode of season two - it appears to be a tall, slim men). Patrick did see him. He knows that. So why would he put Smith there?
2. Have you noticed that, whenever he watches TV, Jane whatches TIGERS (or other animals) going after their prays and catching them? Is he trying to find out something, or does he just have a guilty pleasure in watching other creatures suffering? And, more important, it appears to have this in common with Red John. I think he`s analyzing the tyger`s behavior in order to discover why did RJ recite the "Tyger" poem.

*Just a thought: I think all the 7 suspects have something in common; one of them is the real RJ, and the other six are related to him somehow. 

And I saved the best for the end: We see a trailer of the second episode of season 2 where Jane says that all this time he has been one step ahead of RJ. My guess? THE LIST thing.
When Kirkland broke into his room and discovered Jane`s work, it was, obviously, a trick carefully orchestrated by Jane. So I think Jane had a sort of game in mind, like "whoever will broke into his roof has something to do with Red John: maybe he is an informant, or maybe he is the actual Red John". There`s the trick, I guess. I think the in Jane`s mind there are less than 7 (now 6 remaining) suspects. My guess? He already has a top three. 

Just for fun... The other day I watched movie called 7 psychopaths and was saying to myself how strange it would be if someone from red John's list would turn up... And to my surprise someone did show up!!! I was  what the heck!!!

Do you wanna know who did turn up?

Most people believe that Kirkland being red John is to obvious, but I'm a firm believer of Occam's razor. Every time we see Kirkland it's related to RJ. The first time we see him is in the flashback which shows he has been watching over pj during his whole CBI career, when he meets and SHAKES pjs hand the red John theme plays in the background, plus he is shown killing of an RJ accomplice and he also got himself all of James RJ research which whould explain how RJ knew the seven names. He is creepy and intelligent which are defiantly two personality traits RJ whould have. I'm 99% sure this guy is RJ but heller is that brilliant you just never know.
