Red john, as was said earlier, was a member of visualise, and his current age shud be 25 years added to anyone below 30, so his maximum age is 55 and his minimum is 35. Then we get to know that he has 3 dots on his left shoulder, which indicate him being part of / in charge of the organization tyger tyger, i personally think he is in charge of it, as he is as smart as jane , perhaps even smarter, and i doubt someone of such an intellect would stick to an organization which he didnt form. So we are left with an intelligent, possibly rich person, with lots of connections, very devious, cunning, he is probably someone we wouldn't suspect, but we aren't PJ, he probably figured out who RJ is from the message that was sent to patrick, and with the list which RJ predicted patrick would conclude, we have to think of it, from red john's perspective. If you were red john, you would probably panic, or be very cautious about mentioning your own name in the list of the adversary, yet if you don't mention it, and patrick the name on his list, then it won't take him long to figure out who you are, so what do you do? you put yourself in patrick's shoes and forget that you are red john. That is why, we are unable to say that the list is real or fake, but personally, i think that it is fake. None of the people of the list, fit the criteria of red john, so who does? there is only one answer: who could have befriended patrick had he desired so? who got close to Lisbon and would have got her love had he wanted so? the answer is simple: W.M. : Walter Mashburn. He is the only person that comes in mind.
