Surprise, surprise. Red John isn't really a man. He is a She: Red Johanna. Sex-lust bionic vampire sent from outer space.

And actually this isn't the real world. This is the matrix. And Red John is the one. The one with red hair (also bottom). Take the Red pill. 

Red John saw, that Patrick Jane and his family are/were Agents. Agents must be eliminated. Partridge is the Morpheus. The red face is remainder; this world is not real. 

It's inception. Patrick's family is dead. But it was Patrick, under inception. Incepted my Kimball Cho. Hard from behind.

Yeah.
