Red John is Patrick Jane

It's Jane himself with a split personality. He had a screwed up childhood, causing his alter personality which killed his own family. He's chasing himself and doesn't know it.

Jane could have done this subconsciously, his mind is intricate enough for this to happen. We all like him but it can't be denied he's manipulative. I think that during his subconscious phases where he resorts to being Red John he has arranged with people plans. I think his seven main people for these kinds of arrangements are the same seven people he has put into his final suspect list.
There are lots of reasons for Jane being Red John, read any of the other theories they're more or less the same. But what really makes me suspect him is the show itself and they way it picks its killers. They always throw lots of obvious suspects at you with reasons that make perfect sense but it always ends up being the person you like or sympathise with the most that turns out to be the killer. Out of every single character in the show Patrick Jane is the most beloved, in their mind he's the ultimate final answer to this case. Oh, and I just love the idea of him naming his seven suspects/helpers each after the seven deadly sins.

Till the whole Timothy Carter death thing it was Timothy who was RJ, but later i think PJ is continuing those murders as a person with  mental disorder.i think that after this with TC, PJ sort of snaped, poped like a popcorn..with faces changing from RJ to PJ..i mean who could ever know things that only Jane knows...and the whole hand shaking thing..i believe its maybe not the physical hank shake...but maybe the psychical hand shake between the PJ personality and RJ personality..

Here are some things i would like to point out : 

...in the season 4 where Jane is talking to Lorelei she says why did they never became friends when they are so alike...i did not see anyone soo damm alike to Jane in the episodes

...and the face RJ drawns with blood is just like Janes face...

...why there were no RJ killings while PJ was in Las Vegas for 6 months...

...how the hell did Lorelei found him in Las Vegas?

....why was exactly the CBI dude Luther Wainwright the one who got caught by RJ...if i remember he and PJ were insulting each other the episode before...and RJ does not like to be insultet in any way..so LW ended up dead...why it was not hmmm...Lisbon? Because PJ likes her and think as a friend/crush

...and now you will ask me what are the other suspects doing in the series...and i wil tell you that they are nothing but distractions...just to keep us away from Jane in the first place....and on the other hand doing misunderstandings with PJ s mind...like for example the girl in the graveyard was sent from a disciple just to mindfuck PJ and the person with the baseball hat could be any of them...

....in the series we can see that PJ is very good at faking things...from his mental acts to his behaviour...like when he was in a verbal fight with Luther, even Lisbon believed all of that but it was just an act....

...somehow RJ is always one step ahead of PJ...wich is impossible...he knows his every move, his every tought and his every trick...

....in my opinion this all is just to turn PJ a RJ himself at the end and to make him crazy

...when PJ lost his memory he was a complete different person....

...nobody did not know about the meeting between Gale Bertram and PJ....

...how did RJ knew that PJ is going to the graveyard just when he saw the happy anniversary note on his car...PJ when arrived there was not looking around for RJ, but he was looking in the graves, and why he hipnotized the girl and said to Lisbon RJ could kill her...he could instead leave her go and follow her...

...also there is a big black hole in the series when James Panzer was killed by RJ...it was a great moment for PJ to follow Panzer privately just to get in trouble with RJ as he always did before...but this time he didnt....

...why is PJ keeping all the sudden everybody away from RJ...ok, he says that if anybody talks about RJ ends up dead...but i think there is something behind that....i think that PJ usually wouldnt care that much about others and that he would try to set a bait for RJ in that way....

....why didnt RJ take for example Van Pelt, or Cho, or Rigsby in the limo but exactly Luther wich PJ didnt like so much...and why is the group VP,Cho, Rigsby and Lisbon safe for 5 seasons now...

...why did RJ wanted to "have fun" with Darcy instead for example Lisbon wich is also helping to solve the RJ case with PJ...

...how come that Christina Frye is alive but was in contact with RJ....he hipnotized her wich is the thing Patrick does...and PJ does not kill her as RJ because he liked her..

....the voice in the limo sounds like PJ...

...."does anyone know who you are?"...charlotte asks PJ while halucinating...

....i am just not sure if PJ is RJ frome the beginning or it is half Timothy and half Jane...

...i think that when RJ was thinking it was time for him to approach was the time in the mall..because he knew he has done his job but wanted jane to continue it...so jane with the mental disorder did so...but when the Jane persona was more powerfull in his head than the RJ persona then the disciples and the clues where there to mess up janes head again...

...and whats with the happy memory thingy only Pj knew ;)

.. Also Red John guessed all the suspects correct which is impossible since how would he know which people did Jane shake hands with.

...Its feels like Jane is Red John. Whether its a case of multiple personality disorder perhaps..

....i really love PJ as a character and would not like an ending where Lisbon has to shoot him or something like that :( 

PJ İS OF COURSE RJ

So many suspects, so many logical answers to the question that's been haunting my mind for the past 5 seasons of The Mentalist. Who is Red John? To be fair you could likely come up with a logical defense for every person on Jane's final list of 7. I have chosen Jane as the "Accuse"d simply because I have to chose someone and if you're simply and solely interested in that skip to the very last paragraph. However I have not actually decided myself if I truly believe that Jane is Red John.

Starting off with Brett Partridge who has been my #1 for a long time now, fits the physical description given by Rosalind Harker, as well as the creepy persona given off by him whenever he is at a crime scene with Jane. Personally I don't think there's enough substance however to allow for this, you have to realize, there has to be more than just a physical description and a creepy persona for the literal jaw drop that will occur when the name or names is/are finally released. 

"Names" you probably noted I used in the ending of the last paragraph, now this is a new theory I have recently come upon through pictures and other theories I've read. I'm sure most of you are aware of the

"He Is Mar" scene where one of Red John's victims was killed and supposedly left "He Is Mar" on the wall. I don't feel comfortable developing any kind of conclusive response to this as I feel without further evidence it can go both ways. Instead I will leave multiple points around it any my opinion. It should be noted the extreme caution and care that Red John has had up until this point, to the extent similar to Jane, do you really think it's likely for him to have been so careless and so sloppy to have left the suspect alive and able to right a message that could potentially end his time as the infamous Red John? "He Is Mar" in that order and shape seen in the actual scene itself couldn't really amount to much, what words start with Mar that could be so conclusive someone would choose that over anything else to right when dying. Instead I think it would be more likely that it was meant to be something else, turning out to look like "Mar". http://gyazo.com/07130735723473056f379666645a48da
For example, "He Is Jane", or "He is Many" both can be seen if you look carefully. If you don't understand what I mean by that, or can't see it, simply Google either one of those quotes and i'm sure you'll find something.

I could probably go on for hours and hours sitting here typing out theories both supporting and rebutting each argument around each of these 7 suspects, but to be honest I feel you cannot make any kind of certain conclusion without further evidence, cause hey if it was that easy someone would have a conclusion that would be widely accepted by now. For a final point I leave you with this, something I have to wrap my brain around. In one of the few scenes Red John is seen in, where Rosalind is on the phone with if my memory suits me Jane, we see the arm and hand of the suggested Red John, the thing about TV and crime TV especially is that nothing is coincidence, the one thing i find notable about that picture (linked below), the tea cup, and who do we know who loves tea? I know he's not on the list but Tea has been HUGE for Jane in every season, HUGE. Nothing is coincidence. The smallest details are what makes the difference.
