He has opportunity being at his position. His abruptly departure to stay behind the scenes when everything was getting close. I think he brought Patrick Jane in to torment him.

Has anyone taken into account that the list is a "Red Herring." Jane was prepared for someone to break into his room and steal his research. He even smiled when he noticed that someone broke in. So Jane being Jane would have misleading info available. Although I believe Bertram, Smith, McCallister, and Partridge are(and were) disciples of RJ, they are not him. Hafner, who is creepy, works for Brett Stiles. Stiles is crazy and sadistic, but scared of RJ. I feel RJ and Stiles have a rivalry going since the beginning of the cult. Stiles wants RJ because he took Stiles' son, Partridge. That's why Hafner is sticking so close to the case, for Stiles. Lastly, Bob Kirkland...... He's just too obvious. 
That is why I believe Virgil Minelli(who is approximate in age to Bret Stiles) is RED JOHN. Someone who Patrick shoke hands with, but never became really close to.

P.S.
RJ should have killed Lisbon, but didn't. Minelli would have let her live because he liked her.

i dont think RJ is any name in the list. it's meant to distract him, really, since PJ smiled when he saw the broken toothpick. My best guess is all the name in the list are all his disciples and he'll kill them all one by one, just to prove he's smarter than jane...

Honestly I think RedJohn is Virgil Minelli. If you look at the seasons that is as head of the brigade always has to go away, and curiously during these trips, RedJohn appears during the absence of Virgil.

Could it be to withdraw from the squad to devote all the time to Patrick?

The thought that Patrick Jane is RedJohn would be disastrous for the brilliant career of this series, so do not contemplate.

Sorry my text, Google Traductor :)

Season 4 Finale : 

Red John : Oh, you strung me along for a good long while. Congratulations. Fortunately, I have a friend in the FBI, so I found out when the FBI found out.

Season 5, Episode 5 : 

Schultz : I would like some updates on the Red John Case...
Minelli : To put it bluntly Alexa, why would I do that??? What's in it for me ???
Schultz : Well, it's always good to have a friend in the FBI, isn't it???

Also, I believe Tommy Volker could be a friend of Red John (Not accomplice, a friend)

I thought McAllister was red john but then I went to see the William Blake's wikipedia page and I saw that in 1821, an illustrated book is named  " R.J  Thornston, Virgil."

oh yeah, I know your thoughts

Listen to the voice that laughs at Jane in the hookers phone, and he is just mysteriously gone during all of this. He has access to the secure sight. But of course he has help.
