Red Herring
Remember the interview of the alleged Red John. He said he was surprised because he thought he was just a red herring.
Interview with Lisbon
The Mentalist's Robin Tunney(Teresa Lisbon) has revealed she was "surprised" when she found out the true identity of Red John. https://tinyurl.com/mhzcd5d
Interview with Brett Partridge
Let’s say you turn out to be Red John, is there something about your character that you would've liked to incorporate from the get go, or are you fine with not having known the whole time?
Jack Plotnick(Brett Partridge): Well, I played it like I was Red John from the beginning.

Remember nobody knew who was playing Red John in the cast until a few weeks ago.
There are several theories here, and Bruno Heller has thrown out so much clues that almost anybody could be Red John. Just so much clues, every viewer could see it the way he wants it to be. Everyone has his or hers own Red John.
