If Obi-Wan had faced Sidious, not only would he have died, but all hope would have also been lost in ever defeating the Sith and bringing balance to the Force. It was a tough decision, but
Originally Answered: Could Obi Wan defeat Palpatine in a duel? No.. He can not.. And BOTH Yoda AND OBI WAN himself SAID SO both in the movie and the book Revenge of the Sith.
DARK SIDE FRIDAY - Did you know Palpatine feared Qui-Gon Jinn? Palpatine was immensely powerful and he could see the future which made him very confident about pretty much anyone who stood against him. So why Qui-Gon Jinn?
Yoda believed Obi-Wan was no match for Sidious (he would be a liability just as he was when Yoda fought Dooku): and that the chances for the Jedi's survival were better if they didn't put all their strength towards one suicide mission.
Palpatine absolutely did NOT fear Kenobi as a physical threat to himself. Could he have beaten Obi-Wan in a straight lightsaber duel?
As powerful as Darth Sidious may have been, it's easy to forget he actually seemed afraid of Master Yoda. As seen in Revenge of the Sith, Palpatine initially thought he could deal with the aged Jedi Master - and then, when Yoda proved able to counter the Sith Lord's Force lightning, he fled.
He dedicated himself to growing in power, ultimately disposing of his master once he had attained sufficient knowledge. And while Yoda and Palpatine both worked with the Senate, they treated each other with the utmost respect.
The Emperor wanted Vader to bring Skywalker before him, so he could be turned to the dark side. Despite Vader's seeming loyalty to the Emperor, Palpatine wanted to replace his servant with a new apprentice, while Vader plotted to overthrow the Emperor so he could rule the galaxy with his son.
After battling Palpatine, he realized the Sith had grown far stronger than the Jedi and that his years of training had failed. Though the Jedi had taught the same teachings for over a thousand years, the Sith had been using the Rule of Two to evolve and better themselves.
Sidious himself felt that he and his peers had outgrown the use of lightsabers, and only continued carrying them to mock the Jedi. He ultimately viewed his own lightsabers as little more than an affectation, and rarely wielded them in combat.
If Qui-Gon had survived his fight against Darth Maul, he would have sensed Palpatine's evil, and Anakin wouldn't have become Darth Vader. Thus, while Qui-Gon was less powerful than Yoda, Palpatine feared him more. Your browser can't play this video.
It's implied that this isn't feigning and Palpatine is actually fighting to win. In the book its implied that he allows Mace to move him and make certain moves, however this is a not uncommon dueling tactic, waiting for openings and surprising an opponent.
Even after his brutal scorching in the fires of Mustafar, sand remained the only natural phenomenon that Vader feared. To him, sand was a reminder that he'd failed to save his mother or Padme from death.
One of the main reasons why Yoda would've won against Anakin is simply because he was far better trained than him. Yoda could see the moves his opponents were going to make before they made them; therefore, battling against Anakin would've put him at a far heavier advantage.
As the grandson of Anakin Skywalker (on his mother's side), one of the most powerful Force users in the galaxy, Kylo Ren has the appropriate bloodline to destroy Palpatine. It was a redeemed Anakin Skywalker who killed Palpatine the first time, and the same midi-chlorians flow through Ren's veins.
throughout many of the Legends storylines, Vader sought to hunt down every last Jedi. while Palpatine was no longer concerned with the Jedi. Order, in his eyes, Yoda and the Jedi no longer posed a threat to his role. during the early years of the Empire, Palpatine only sent Vader to hunt survivors.
In Star Wars: Return of the Jedi, Darth Vader felt defeated and more importantly trapped, again. He was still reeling over Luke's rejection of his offer and felt that at this juncture, he was far too gone to the dark side, so he might as well remained loyal to Emperor Palpatine.
Star Wars creator George Lucas has stated that the reason Palpatine couldn't anticipate Vader's betrayal in Return of the Jedi was that he can't truly understand the concept of love.
The short answer is yes, without a doubt, Vader regretted becoming a cybernetic monstrosity. First, there's the constant pain and discomfort from his suit. Worse, however, is the psychological pain. Vader destroyed everything he had ever known for a chance to save Padme.
Dooku voluntarily left the light side behind and became Darth Sidious' dark side disciple, taking the secret name Darth Tyranus and leading the Separatist army. Dooku advanced Sidious's secret plot to take over the galaxy, but forgot that betrayal is the nature of the Sith.
He was still completely unaware of the Sidious/ Palpatine connection until ROTS. He also said during TCW season 6 that the Jedi order must believe in the clones and end the war before the Sith's plans are realized.
A Sith Lord with the ability to cheat death and create life, Plagueis is the mentor of Sheev Palpatine / Darth Sidious, who, in accordance to the Sith's Rule of Two, eventually betrays Plagueis by murdering him in his sleep, taking his place as Sith Master.
