The Meaning behind The Sith Code

Some have speculated that the Code of the Sith was created in direct contrast with the Jedi Code, to illustrate the fundamental philosophical differences between the orders. This could certainly account for the first line of the Sith Code discounting the Jedi's proclamation of peace, as well as the similar structure of the two Codes.

The Sith saw themselves as seekers, challengers of old and stagnant ways, in touch with the laws of nature and the universe. They saw the Jedi as denying their natures and afraid of the truth around them. Yuthura Ban gave examples of the tuk'ata and sarkath hunting prey, feeding on weaker creatures. Passions were what kept all creatures—from the most rudimentary to the most evolved sentient—alive. Yuthura Ban explained this to the amnesiac Revan, "To think us creatures beyond the need of simple passions is a delusion." They believed that mastery of their passions gave them strength the Jedi lacked.

The Sith did not believe that victory by any means was desirable, but believed that unless victory proved your superiority, it was an illusion and temporary. Though there might be different types of victories—peaceful victory, victory by sacrifice, even a truce—Sith dogma taught that unless the victory was achieved by demonstrating that one's power was superior it was not true victory. The stronger a Sith became in the Force, the more power he could achieve, but he always had to fight for that power.
