Redemption

Movie: Star Wars

While not actually a movie but rather a series of movies, Star Wars presents the character Darth Vader as an evil mastermind and leader of the Empire, of which they are aligned with the dark side. However, a prophecy states that eventually, he will be the one to bring balance to the Force (Basically, the moral balance of the world) by destroying the dark, which he eventually does by sacrificing himself to kill his master, Darth Sidious. The redemption is seen through him killing Sidious because he brought balance to the force as the prophecy stated as well as atone for his previous actions of nearly destroying the Jedi (Organization that was affiliated with the light side) and ruling over the galaxy with an iron fist.
