I figured it out. Red John is actually a gay guy who is in love with Patrick Jane. However, since Patrick was married there was no way he could be with him. So Red John killed his family so Patrick would become single. In the end, when Patrick finally has Red John, he will realize that he has actually enjoyed all this chasing around and has fallen for Red John as well. The last episode will be them getting married. Once Lisbon finds out Patrick and Red John are getting married, she is sent (by the illuminati) to kill Patrick for being a homosexual and not being in love with her. Since Bruno Heller is a well known gay activist, it becomes obvious this show is a metaphor for why Gays should be able to get married in all 42 states.
