After he became Kylo Ren, he started to admire the power of his maternal grandfather Anakin Skywalker, but particularly in his Vader incarnation. His attachment to Vader makes him desire to uphold the Sith Lord's legacy by destroying all the remaining traces of the Jedi tradition.
Not only did Ben care little for the Jedi, he also viewed Luke as the person keeping him away from his parents. And the strict rules of the Order only made matters worse, as Ben felt they limited his potential, and forced him to forgo attachments.
He saw her as a useful tool for his rise to power. He was intrigued by the mystery surrounding her. He wanted closure for his defeat at her hands. He had a genuine emotional connection to her.
Ben Solo only discovered the truth about his grandfather when Casterfo revealed it to the Senate, which means Leia had lied to him for almost 20 years. This discovery is what led Kylo Ren to finish what Darth Vader started and began his obsession with following in his grandfather's footsteps.
The son of Han Solo and Leia Organa, Ben Solo was seduced by the dark side of the Force and renamed himself Kylo Ren: leader of the Knights of Ren, champion of the First Order, and apprentice to Supreme Leader Snoke. Driven to destroy the past, Kylo killed his father and his master, supplanting Snoke as Supreme Leader.
But this is actually a very sad reason because it actually had the opposite effect, and he deeply regretted his decision to kill his father and it haunted him for the rest of the trilogy. Also, Han was telling him that Snoke was using him, but one of the reasons he killed him was to impress Snoke.
Kylo Ren's "unstable" lightsaber was designed to kill. Knowing Makashi, he would become a much more dangerous foe as he could disarm and eliminate his opponents far quicker without the need to endure a long, intense fight. Sadly, he didn't learn Form II as there was no one around to teach him during his younger days.
In fact, only one act ever truly qualified as a Sith act, no matter how hard he may have tried to prove himself to Snoke, and Palpatine, by extension, during the Star Wars sequel trilogy. This is one of the reasons why Kylo Ren was never an actual Sith – instead, he was a dark side adept.
The lightsaber Kylo Ren longed for as his birthright was instead claimed by Rey on Starkiller Base. You need a teacher! I can show you the ways of the Force!" After incapacitating Finn, Ren attempted to summon the lightsaber to him, regarding it as his own property due to its history.
Had Lord Vader not succumbed to emotion at the crucial moment -- had the father killed the son -- the Empire would have prevailed." That means Kylo was aware of the redemption and frequently reminded of it. Kylo chose to idolize his grandfather for what he once was, viewing him as Darth Vader and not Anakin Skywalker.
The Rise of Skywalker novelization insisted the kiss was not romantic, explaining that it was “a kiss of gratitude, acknowledgment of their connection, celebration that they'd found each other at last”, but when looking at the context and what their connection was like since The Last Jedi, the kiss between Rey and Ben ...
When Rey went to meet him on the Supremacy in an attempt to convince him to turn to the light, Snoke reveals that he had manipulated their bond to lead Rey into a trap and starts to torture her in front of Ren. This infuriates Kylo, who at this point had developed strong feelings for Rey.
Summary. Rey gained knowledge and skills through her connection with Kylo Ren, allowing her to tap into his training and skills. Kylo Ren was wounded by Chewbacca's bowcaster, which he believed inhibited his ability to defeat Rey.
Though Supreme Leader Snoke claimed that he was the one who linked their minds, The Rise of Skywalker revealed that their Force connection went back much further than that. As a dyad in the Force, Rey and Kylo Ren were uniquely connected as one in the Force for most of their lives; they just didn't know it.
I suggest that when Ren's emotional outbursts, impulsivity, and unstable self-concept are looked at more closely, there is plenty of evidence to suggest that he suffers from Borderline Personality Disorder and that perhaps he is simply not just a cold-hearted villain after all.
This caused him to attempt to assassinate him in his sleep. Needless to say, Kylo Ren is almost definitely a significant threat. However, we cannot definitively say that he is more powerful than Luke. Kylo's powers are vast but they are still highly unbalanced and difficult to control.
Traditionally, yellow lightsabers are associated with Jedi Sentinels, who balance their combat skills with a strong focus on exploration and practical application of the Force. This choice reflects Rey's well-rounded training and her determination to maintain balance in the Force.
By the time Rey touches the weapon, Anakin has long been redeemed, and the essence inside the Skywalker lightsaber is constantly calling her to learn the ways of the Jedi and fight against the dark side in his place.
However, joining the Sith means declaring loyalty to the dark side, which Anakin did before his eyes turned yellow. This may explain why Kylo Ren, torn between the light and dark, didn't have yellow eyes in the Star Wars sequel trilogy, as killing his father split his spirit even more.
The crossguard blades allow Ren's saber to operate safely – his weapon is constructed around a dangerously flawed kyber crystal, which would be overloaded if not for the lateral plasma vents that create the quillons.
JJ Abrams told Empire in August 2015, "Kylo Ren is not a Sith. He works under Supreme Leader Snoke, who is a powerful figure on the dark side of the Force." Abrams had previously stated that the character "came to the name Kylo Ren when he joined a group called the Knights of Ren."
In a galaxy filled with lightsabers of various colours, the Darksaber stands out as the rarest lightsaber colour, shrouded in mystery and steeped in history. Created by the first Mandalorian Jedi, it has passed through the hands of warriors, terrorists, and heroes, leaving an indelible mark on the Star Wars universe.
Kylo lost to Rey in TFA because he was heavily wounded and was holding back against her due to Snoke's request that he bring her back to him alive. He is also stated by Palpatine in the Secrets of the Sith book to be “equally as powerful as a real Sith despite not being one”.
The hilt of Ren's lightsaber also featured a black burned appearance as a result of its first activation without the vents to compensate for the unstable power of a damaged kyber crystal. Compared to typical lightsabers, this weapon had an unusual sound frequency where the ignition hiss sounded crackles and sputters.
