However, the torture that he experienced at the hands of the Emperor had splintered Revan's mind, and while part of him attempted to become one with the Force, the rest rejected death and clung to life, embracing the dark side.
Canonically yes Revan returns to the light side but Revan doesn't remember everything until after the Star Forge and Malak. After that he remembers what actually turned him and Malak. He remembers that the True Sith still exist and have a massive army under a Sith Emperor even more powerful than him or Malak.
However, Revan and Malak eventually found their way to Dromund Kaas and discovered that the Sith Empire indeed still lived. Their attempt to eliminate the Sith Emperor went horribly wrong, with the Emperor dominating their minds and finally turning them to the dark side.
In Legends, Revan was a Jedi Knight who broke away from the Jedi Order, became a Dark Lord of the Sith, and formed a Sith Empire that waged war against the Order and the Galactic Republic. While experiencing amnesia, the former Sith was retrained as a Jedi to confront the Sith Empire, Revan's own creation.
Disney used Revan as an inspiration to create Kylo. His armor, inner conflict between Light and Dark and his use of the Force. Snoke considers Kylo to be the ideal embodiment of the Light and Dark sides of the Force, much like Revan, who was a master at both sides of the Force.
Revan—renowned as the Revanchist, honored as the Revan, reviled as Revan the Butcher, dreaded as the Dark Lord of the Sith Darth Revan, and praised as the Prodigal Knight—was a Human male who played pivotal roles as both Jedi and Sith in the Mandalorian Wars and the Jedi Civil War.

Though a proponent of the dark side, Darth Vectivus' self-discipline and preexisting code of ethics allowed him to remain fair and balanced without succumbing to the lure of power which plagued many of the Sith Lords who preceded him.
"Revan had many Masters, Zhar, Dorak, Master Kae before Kae left for the Wars. Toward the end of his training, he sought out many to learn techniques. It is said that he returned to his first Master at the end of his training, in order to learn how he might best leave the Order."
Rather than leaving Revan to die, Bastila took him to the Jedi Council, who wiped his mind and gave him a new identity as a Republic soldier. Believing he was meeting Bastila for the first time, Revan accompanied her to the Jedi Enclave on Dantooine and was trained as a Jedi.
They were originally led by Darth Maul (who claimed to be the one chosen to seek out Revan's descendant) until he "stepped down" when he took Ezra (who was revealed to be Darth Revan's descendant) as his apprentice and appointed him Mandalore and the offical leader of the Revanchists under the name Keneh Heru (when in ...
Her knowledge of the fact that Anakin Skywalker and Darth Vader are one and the same naturally raised some big questions about her character, especially since his identity was supposed to be a secret. In Obi-Wan Kenobi episode 5, what she knew about Anakin turned into a major plot point.

This mask was originally worn as a part of a Mandalorian female's armor, and had a red and gray color. Ten years after her death during the Mandalorians' genocide of the Cathar people on their homeworld in 3973 BBY, the mask was claimed by the Jedi Knight Revan and was immediately donned by the Jedi.
During this time, Revan wielded a single-bladed blue lightsaber with an alloy metal hilt as his primary saber. Some sources report that he also used a purple lightsaber to represent his independence from the dictates of the Jedi Council.
To put it simply, The Knights of the Old Republic games and novels are no longer canon to the established Star Wars continuity. Following Disney and Lucasfilm's decision in 2012, the games and additional materials covering the Old Republic were all placed under the non-canonical Legends banner.
