Anakin's Dark Deeds

"Anakin's Dark Deeds" is a piece written by John Williams for the Revenge of the Sith soundtrack. It represents the killing of the Separatist Council by Darth Vader, his emotional struggle with the dark side, and to some extent Palpatine's transformation of the Galactic Republic into the Galactic Empire. It was performed by the London Symphony Orchestra and the London Voices in 2005, and contains references to "The Imperial March." It appears again in the video game Star Wars Jedi: Fallen Order when Darth Vader appears. It also appears in Star Wars: The Clone Wars 11th episode of the 7th season called Shattered during Order 66.

In the 2011 video game Star Wars: The Old Republic, "Anakin's Dark Deeds" plays when Anuli is killed by the forces of the Eidolon.

In Star Wars Episode VIII The Last Jedi similar motif is heard subtly during the scene in which Kylo Ren asks Rey to join him after defeating of Snoke and his Praetorian Guard and later it's heard more prominently and louder when she attempted to call to herself Skywalker lightsaber by using the Force but Kylo managed to intercept it.
