Bret Stiles is not Red John. Patrcik knows this ,because he told him at S3E10 " you cannot hurt even a termite" , why Stiles on the list than? Because list is fake. Watch S3E10 again

Who versus to Whom / Who are together

FBI is with RJ. (All his sources within FBI) 
O laughlin was RJ 's man and he was to Visualise. 

Tyger Tyger created by RJ , to fight with Visualize members inside police. SO;

Brett Stiles and Ray Heffner are not RJ and they are good people.

Bertram,Smith,Scheriff are working for RJ within Tyger Tyger.

Kirkland's other twin brother is also working for RJ 

Partridge is uncertain, but most likely death. 

List is fake,Red John is not someone from the list.
