It's basically what Jedi MUST be. Jedi should go with the flow of the force(Like Qui-Gon did). Qui-Gon disobeyed the council constantly, but only because he wasn't caught in their false perception of a perfect world.
Sith are the bad guys. They want power. They want to rule everything. They do it only for their own benefit. Jedi are supposed to be unbiased. They must not have rules such as "you are not allowed to marry anybody", "you are not allowed to love", "you are not allowed to do this and that". If the force is telling you to kill somebody, you KILL him. If the force tells you to help someone(as Qui-Gon did for Anakin) you do it. You don't wait for the council to approve. You are supposed to listen to what the force tells you. This is what Jedi are supposed to be.
