I think Red John is not a human. Yeah thats right not a human. Remember "he is mar"? I personally believe that Red John is an alien and the "he is mar" things was actually he is martian!!! He just couldn't complete it because he was dying. That's why no one wants to reveal RJ they DON'T ACTUALLY KNOW WHO HE IS! They were brain washed by RJ. So there you go that's my theory, I know that it is hard to believe but well its a theory.
