I have been following along but have a few questions of things I don't quite understand about the 7 suspects on the list. As a fan of the show i was quite disappointed with the list

1. If red john and jane both knew the clues then why did reed smith and bret stiles end up on the list? Reed smith is clearly too large to be red john-who is depicted as normal/skinny and according to red barn-red john is much younger than bret stiles.  (obviously i understand most of the evidence is sketchy).  

2.  Brett partridge (and maybe haffner, bertrum) seem the only ones left who could realistically be red john (many other people have submitted evidence why it can't be kirkland, sheriff mcallister, stiles, smith).  if Brett P is red john-isn't that an insult to Jane's intelligence?  Partridge from the start is an obvious creep and way too interested in death.  At this point i think he is the most likely character but i must admit id be disappointed if he is the red john mastermind because i don't think he totally fits the psychological profile (royston daniel and bret stiles seem much closer fits as mastermind).  

back to the point-Jane can feel when red john is around-he does feel creeped out by Brett P but wouldnt Jane be able to sense or figure out Brett is Red John seasons ago.  If he didn't figure out it was brett P then many people died due to Jane's failure.  

3.  Bret Stiles has alluded to he knows who red john is-why won't he reveal or stop red john? is he afraid or a part of it?

I'd appreciate any comments or ideas. Thank you
