A lot of structure of the story line makes Jane look suspicious towards being Red John. If the theory he used to catch the San Joaquin serial killer in Season 4 is applied to Red John, Jane fits in perfectly. He is self- obsessed and likes to make Red John look smart in the eyes of the public. His participation to help the police could have two reasons- to keep the legend of Red John alive. Second, because he is guilty of killing his wife and daughter, something he had to do when Patrick Jane was becoming more believable to people than red john. 
He makes the blogger of the serial killer to put down Red John on a TV interview just so that Red John can come out and kill him? Why would he want to give away his one advantage where everyone believes he has killed Red John to punish the blogger (the killer). Because he does not want any other serial killer to look as smart as Red John. 
Also, when Red John killed Partrick's wife and daughter, he left behind a note, this time there was no note to a man demeaning red John. Later in the season Jane loses his memory for one episode where he is shown as a womaniser and a con artist with no conscience. He says he wears the wedding ring to get sympathy from the women he cons. He also jokes with Cho about his family, which makes the entire story of him even having a family suspicious. What if he never had one, and it was all just a legend he created. 
Finally, all the money that he made of coning people must be used to keep his own agents who would be carrying on their roles apart from his hypnosis technique. Hence a lot agents would further have people working for them, eg- O'Laughline or Loreli. Which is why they don't recognise Jane. 

Clearly the series has gone on too long to end with a simple "it's one of the seven suspects" finale. I think Jane is insane, i think he has a multiple personality disorder that means he is Red John but at the same time he honestly doesen't know who red john is. As for the fact that Martins said he shook red John's hand and the fact that Red Johns accomplices never recognize him as being red John those are easily surmountable pieces of evidence that point against him. How does Red John know about his childhood memories? How does Red John always stay one step ahead of him? Its simple, Red John lives in Jane's subconscious. However there is one thing that leads me to be contrary to this belief and that is with regards to my suspicions related to lisbon. The fact that at the begninning othe season finale she is asked what happen to her hand and no answers are given was dropped in by the writers on purpose. However as with jane there is the whole thing regarding the handshake. I have a very strong feeling that that was just a huge red-herring dropped by the writers in order to fool unwitting spectators.

I believe Jane is saying he had list to bring out red John. He feeding people false info to see who gets it. He tells people he has list and he's narrowed it down. I believe jane played red john to get the list from him. About memory Jane had break down and was just getting out of hospital season one . So his doctor knew and Jane . You can drive your self nuts on this.

FYI - Lorelai died before Kirkland copied Jane's research. So I don't it it was that way that revealed his 7 suspects.

Disappointed that Mashburn, Ardiles, & the Judge aren't on the list of suspects...
...Reede Smith? Sheriff? WTF

When i watched episode season final i think 90% Jane isn't red john:( I was hope If he is red john but pictures made me lose my hope about this theory.... anyone agree with me?

The only match Jane has had is Red John. Have you ever tried to play chess with yourself? The game ends in a draw every time. You cannot outwit yourself.

Also, Jane has red hair - like the Red John logo, and the names Jane and John are too similar.

Actually, I really have it narrowed down to Patrick Jane, Kimball Cho, and Wayne Rigsby.  For me, it's more of a gut hunch on each of these.  As far as Patrick Jane, he always seems to know how the criminal thinks...his past is kind of shady...and he turns his emotions on and off in a rather odd manner -- very similiar to someone with a mental illness like multiple personality disorder.  With Agent Cho, he's just so cold -- doesn't seem to connect much with any of his co-workers -- more like he's observing, so he'll know how to throw them off the track.  And with Rigsby, he's a bit unstable -- too emotional...like a loose cannon.  Like I said, my theories have no solid facts, they're all just a gut hunch...call it women's intuition.  My husband says I'm way off base...he thinks it's the head guy from the church/cult.
