The execution of Order 66 marked the destruction of the Jedi Order. Before the Galactic Senate, Palpatine told the galaxy that the Jedi were traitors who had attempted to kill him and seize power, and the destruction of the Jedi was greeted with applause by the Senate.
So, it's likely Yoda didn't want to interfere and alter the future, as he'd be at risk of preventing the Sith from being defeated many years later. While Yoda sensed that the Sith's plan involved the Clones, it was too late to prevent Order 66.
What If The Jedi Executed ORDER 65 Against Palpatine
What is order 64?
Order 64: Send pink slips to members of the senate. Order 65: Play gloomy choir muzak in new Death Star. Order 66: Kill all the Jedi. Order 67: REVISE ORDER 66 – I meant to say, “BILL” the Jedi for reimbursement of the clone army.
Order 69(AKA "clean up") was the idea to kill the entire clone army in one sitting, leaving the Jedi defenseless and exposed by the sudden departure. Palpatine knows the Jedi's weakness is empathy and most will try to help the clones and now it should be easy to either drive the Jedi into hiding or have them killed.
Vader did not hunt for Yoda in any cinematic depiction. He and Sidious could not find Yoda as he had exiled himself on the planet Dagobah which had strong dark side energy that masked Yoda's presence in the Force.
Rex is one of the most popular characters in Star Wars: The Clone Wars, and it was a relief to see him disobey Order 66 in canon. Rex took Fives' warnings about the inhibitor chips seriously and made an official report on the matter.
All the official Star Wars merch calls him The Child. On the show, they call him The Asset. What gives? The short answer is that “Yoda” is the name of a character, not a species, and the character we see on The Mandalorian is different from the Yoda we know and love from the Star Wars movies.
As the knights in the Jedi Temple made a valiant effort at protecting him during Order 66, Grogu was whisked off Coruscant by Jedi Master Kelleran Beq, played by none other than former Jar Jar Binks actor Ahmed Best.
Darth Sidious, was in the earliest stages of his plan to take over the galaxy, and he was afraid a certain Jedi might get in his way. Interestingly, however, that Jedi wasn't Yoda or Master Windu, but instead Qui-Gon Jinn.
Order 66, also known as Clone Protocol 66, was one of a series of contingency orders that the clone troopers of the Grand Army of the Republic were secretly trained to prepare for during their growth. The order branded the Jedi as traitors of the Republic and called for their immediate execution without question.
As for the evidence that came later, Yoda believed that the Jedi had already lost by participating in the Clone Wars. He wanted to prevent Order 66, but he also feared what would happen if the Jedi gave into fear over visions of the future. Still, it's unclear whether Yoda was right to ignore the warning.
The added risk Darth Vader takes in allowing children to live in a situation where he could have killed them proves that he regrets killing Younglings and will avoid harming any more children for the rest of his days, though intense intimidation is a dark strategy to avoid repeating his Youngling massacre.
Return of the Jedi establishes that Yoda was aware that Anakin Skywalker had fallen to the dark side and become Darth Vader. When questioned by Luke Skywalker, he confided that Anakin was Darth Vader. Later, Obi-Wan Kenobi's Force ghost confirmed that Anakin had indeed fallen to the dark side and become Darth Vader.
As Han Solo, Chewbacca, and Leia were gathered in one location at the same time, Vader and his stormtroopers had the perfect opportunity to take them down. However, because he saw their dynamic as a source of weakness, he opted to spare them.
Born on the planet Hyperkarn in 15 ABY, Rey Palpatine was the daughter of Dathan and Miramir. While their names were lost to history, Rey's father was the cloned son—an artificial genetic strandcast—of the resurrected Darth Sidious, making her the granddaughter of the fallen Galactic Emperor and Dark Lord of the Sith.
During one of these missions she would break the Jedi Code's rule of attachment by falling in love with Darman, RC-1136, a clone commando in Omega Squad, and becoming pregnant with his child, Venku Skirata. The two would later marry in the traditional Mandalorian way shortly before her death in 19 BBY.
During an early assignment as a Padawan with her Jedi Master Kast Fulier, Etain met the clone commandos of the Omega Squad, an encounter that changed how the rest of her life played out. Darman Skirata, formally RC-1136, was a clone commando of Omega Squad that Etain later fell in love with as the Clone Wars continued.
The First Order is a fictional military movement and rump state in the Star Wars franchise, introduced in the 2015 film The Force Awakens. It is formed following the fall of the Galactic Empire after the events of Return of the Jedi (1983).
Order 99 was an order arranged by Jedi Master CaptainR1. It turned the storm troopers back to side of the new Republic. During the clone wars, clone commando "Roger" refused Order 66. He was very close to the Jedi he was fighting with.
The order was only documented being used once, in 18 BBY, where Obi-Wan Kenobi and Ferus Olin were attempting to escape Imperial patrols. This happened while Olin was in hiding on Bellassa in the city of Ussa. However, Kenobi believed that the clones would not honor their ultimatum and execute the prisoners anyways.
