Ahsoka's departure haunted Yoda for a long time afterwards; he felt extremely guilty and remorseful, partly for refusing to stand by her and partly for placing her on the path that led to her departure from the Jedi Order. In fact, his guilt was so great that the dark side tried to use it against him, but failed.
Yoda Blames Himself For Yaddle's Death By Count Dooku's Hand
Obi-Wan senses that Yoda has essentially given up, on the galaxy and on himself. Yoda blames himself for the fall of the Jedi and the rise of the Empire, so he's decided to take himself out of the equation entirely.
Yoda Made an Attempt to Repair Broken Relationships
While this brought peace to his people, it was an uneasy one. More so, Yoda felt like he failed, as he never wanted a young Bree to become a killer, thinking he taught him better.
Yoda realized the faults within the Jedi Order, including their militaristic nature and refusal to accept criticism, leading to their downfall. The Jedi's practice of recruiting and isolating children from their families was a major flaw that Yoda acknowledges and regrets.
The ONLY Time Yoda Turned to the Dark Side - Star Wars Explained
Did Yoda feel bad for Anakin?
When Anakin fell to the dark side and became Darth Vader, Yoda was saddened, but firmly believed he was beyond redemption and forgiveness, and ordered Obi-Wan to hunt down and kill him. Even as a Force spirit, Yoda continued to believe that Vader was irredeemable and there was no good left in him.
During Star Wars: Revenge Of The Sith, one pivotal climactic moment shows that Yoda very briefly gives in to anger, nearly falling to the Dark Side. After seeing everything destroyed by Order 66, including all the things he'd worked so hard to help build, Yoda would have every reason to want to strike down Palpatine.
Master Yoda is one of the most powerful Jedi to ever live, fighting alongside the other Jedi for hundreds of years and eventually coming to serve as a member of the High Council during the Order's last days.
So… I'm going to go with 900 years old. The last words Master Yoda utters to Luke Skywalker before his death in Return of the Jedi were: “There is another Skywalker.”
Master Yoda knew that Darth Vader was once Anakin Skywalker - the boy he sensed too much fear in to train way back in Star Wars: Episode I - The Phantom Menace. For many years it's been assumed Master Yoda was aware from the day Vader gained his cybernetic enhancements and signature wheeze.
Thus, Yoda's bizarre way of speaking was designed to highlight what he was saying. Yet it was also designed to make sure that viewers weren't stuck reading subtitles the whole time. That way, Yoda could sound like an alien while still technically speaking English.
Yoda's presence on Dagobah was likely hidden due to his mastery of Force Stealth and the planet's connection to the Force. Yoda, with his enhanced Force abilities and potential home-field advantage, would have had the upper hand against Darth Vader if they engaged in a lightsaber duel.
Yoda is one of the most revered Jedi in Star Wars lore, but the character is best known for his time in exile on the swamp planet Dagobah, plagued with guilt for failing to stop the Sith from rising and the Jedi Order from falling – in Star Wars: Yoda #10, Yoda wrestles with the many tragedies he holds himself ...
Most viewers have forgotten that Palpatine seems to have been afraid of Yoda in Star Wars: Episode III - Revenge of the Sith - and even tried to flee from their duel.
Palpatine both feared and respected Yoda, with some faint contempt. Yoda held his ground whilst battling Palpatine at the Senate building and demonstrated that he could match the Sith Lord in raw power, even if he did fail in defeating Sidious.
Though he did not directly encounter Yoda, Vader's meticulous investigation and strong understanding of the Force allowed him to deduce that if Yoda lived, Dagobah was likely where he now hid.
It seemed Yoda had it all as a Jedi, but he also had a major weakness that most Jedi Masters shared: complacency. Yoda and his peers were too used to the Jedi Order's success. Yoda's complacency meant he was too late to take on the Dark Side until it was too late, and Darth Sidious had already risen to power.
Throughout the Phantom Menace, Attack of the Clones, and Revenge of the Sith, Yoda talks normally until the end of Revenge of the Sith, when he is at Kashyyyk and senses that many Jedi have been slain.
A year later, in 4 ABY, with his health rapidly declining, Yoda died of old age when Skywalker returned to see him. He became one with the Force, shortly before Luke redeemed his father Anakin, who fulfilled his destiny as the Chosen One by killing Sidious.
Neither lightsabers nor the Force could help Yoda defeat Darth Sidious. Though Yoda was able to keep his adversary on his toes, he was unable to end the conflict, and their duel ended with no clear victor.
Yoda didn't want Anakin trained. He considered him to be dangerous, full of fear which could potentially be catastrophic. As it was. The Council refused for Anakin to be trained but the situation has changed after Qui-Gon died.
Legend had it that Yoda—a Jedi who became Grand Master—was trained by N'Kata Del Gormo. A Force-sensitive Hysalrian, N'Kata Del Gormo was trained in the ways of the Force and achieved the rank of Master within the Jedi Order.
While this is not a fight that ever happened or ever will happen in a canon Star Wars story, it is one of the most interesting hypothetical matchups between two characters in the universe.
