Summary
Throughout theStar Warsfranchise’s long history, there have been many different Jedi that have fallen to the dark side. Whether disillusioned byOrder 66, drawn to power, or falling for what one might consider good reasons, there are many different things that could cause a Jedi to turn to the dark side. Sometimes, these Jedi can even be redeemed and brought back into the light.
What qualifies a Jedi for this list is that they must be someone who fell from the light side in the Jedi Order. This is why someone like Reva Sevander, who vowed to kill Anakin Skywalker as a child, is on the list, whereas Osha Aniseya, who left the Jedi Order and did not consider herself a Jedi, is not. Keeping this in mind,here is every Jedi that has fallen to the dark side inStar Warscanon.
