SO HERE IS MY THEORY. IT MAY BE NONSENSICAL AND STUPID BUT TRUST ME THIS IS WHAT I THINK
There are basically 2 organisations. The CORRUPT LAW ENFORCEMENT GROUP(CLEG) and the VISUALIZE CULT GROUP (VCG) .
Red john is being funded by Visualize and that is why he got most of his resources from and probably Bret Stiles is behind it too. The CLEG is probably are a bunch of high ranking corrupts that do dirty works within the law enforcement which uses the code word tiger tiger.I bet Lisbon is also part of it somehow. The organisation have been hunting down red john and also using the work of red john to do the killings at some point. Red John at the other hand being hunted and framed by CLEG tries to lead Patrick to find out about the CLEG by giving him clues firstly the tiger tiger poem. Patrick at the same time is being used by the law enforcement group especially Gale Betram to get information on Red john. Red john is trying to make patrick think that he is a part of the CLEG. Then he wanted patrick to eliminate the key members of the corrupt law enforcement group. The 3 hooligans which is Gale betram, smith and mcallister. Ray Haffner and Bret stiles are on the same side and pretty much working together, supporting Red John and not RED JOHN THEMSELVES. I may not think that Bret stiles is red john father but that might be an interesting plot. Taking down the CLEG was red john prior motive. Red john is a charming man who could easily bring women down to his knees and money to make a man does his dirty work. Bruno Heller said red john was there from the start. We just don't know who but I KNOW ;) Red John , from the description given and from clues of s06e01 and s06e02, is and will obviously be Bret Patridge :) If not then it could be a disappointing Kirkland theory or the absurd Ray Haffner theory or worst an unknown who make his first appearance on season 6 as Red John
