Star Wars: Every Sith Who Turned To The Light Side

Ajunta Pall has the distinction of being the first Jedi to turn evil. While in the Jedi Order, Ajunta tried to create life using his vast knowledge of alchemy. When this practice was banned by his peers, he researched other methods to create life and indirectly discovered the Dark Side. Believing this power was far greater than the Light Side, Ajunta convinced several of his comrades to join him and form a new order called The Dark Jedi. Over time, this faction became known as the Sith, making Ajunta the first Sith Lord.

3,000 years after he died, Darth Revan communicated with Ajunta's Force ghost, hoping to gain insight into the Sith. Ajunta told Revan that he had been tormented by his failure for millennia and regretted forming the Sith. Revan redeemed Ajunta for his transgressions, making him the first Sith to turn to the Light Side after death.
