In a sense, the Jedi and the Sith are different sides of the same coin. They are the extremes of what some may say is the same ideology. The Jedi believe in control over themselves, their emotions, and control in everything else in the Galaxy through peace. The Sith, on the other hand, believe in power; power to shape the Galaxy as they see fit. And while the Jedi believe that anyone should have the power of control over their lives, the Sith believe that anyone should control the amount of power they can individually achieve.
