The Council can trust a Jedi to answer when he is called upon, and a Jedi can trust the Council not to spy on his activities. Dooku's fall to the Dark Side wasn't known until AotC. His official reasoning for leaving the order was that he became disillusioned after the death of Qui-Gon. Many Jedi have left the order for philosophical reasons that aren't Dark Side-related, and the Order makes no attempt to stop them. One in particular was even shown to come visit the Temple and catch up with old friends on occasion.
But that is all just meaningless EU stuff, isn't it? That stuff gets over written all the time. At one point Boba Fett was a Rorschach-esque self-righteous young man named Jaster Mareel. Now, I bet if you even so much as mentioned Jaster Mareel over at a place like TF.n or SW.com you'd get lynched.
Those stories are just made up by various sci-fi writers who get paid for it, if one day George or the creative forces behind the TV show decide to do something that contradicts those books, then suddenly they become irrelevant.
As for Sifo-Dyas being an example, do we even hear anything about him for him to be an example? I though Sifo-Dyas died before ording the clone army, which means he is not really the one who did it, right? Is there anything about him mentioned in the movie beyond, "Jedi master Syfo-Dyas..." "Sifo-who?" "Sifo- Dy-- Ah, screw it! He isn't even important to the plot."
