I've just finished watching "Sherlock" and I realized something:

Supposing that Sherlock Holmes and Patrick Jane have similar skills,
(They do have a lot of common skills, like extremely high observation, arrogance, narcisism, they consult the police solving crimes etc)

Then, Moriarty and Red John should also have similar skills.
Well they don't.The way Red John appeared in the 8th episode makes me state that.
When Sherlock meets Moriarty, he has a gun.But Moriarty has 3-4 men pointing him with snipers.
When Patrick meets Red John, he has a gun and a pigeon (well...) and Red John has Cordero (HOLY crap) and a lady with a knife?

OK, don't get me wrong, but Red John is gay. I was watching the series and I've been obsessed with Red John.I started to be on his side, just because I wanted the hunt to go on.From what we watched for 5 seasons, He was a human being far beyond others.Elegant, strong, determined, secretive, clever, manipulative, he was there and he wasn't there.He was extremely educated, sophisticated, arrogant, playful, he managed to take advantage of the pain of the others and turn them on his side eventually.He killed because he had mental issues and a childhood wound that made him hate women and use them only for sexual relationships.He is a common psycho?No.Because he is like Patrick.And Patrick has something that common people don't have.

And then we watch episode 8.Red John appears to be totally predictable, dumb as hell, sexomaniac, pervert, scared by a pidgeon and afraid of death.This man, this man has killed over 40 people, manipulated thousands of people, seduced the sexiest women, still he is afraid of death and he calls 911.Season 4 finale:
PJ: "Go to hell"
RJ: "As you well know Patrick, there is no hell.When I die I won't be punished."

So,why he is so much afraid of dying?I don't know the creators really messed up.

Red John is meant to be someone that fulfils all those things that they have shown to us the first 5 seasons.That's why people refuse to believe that RJ is dead.It's not the Sheriff, it's not the actor.It's the attidute.

And only one question comes to my mind.

WHY?

Great theories here, if only Heller could just decide to copy one of them.
Don't mean to disapoint you guys, I want is as bad as you want it, but Red John isn't coming back.(Fingers Crossed)
