Because of Qui-Gon jinn. He believed Anakin was the Chosen One and so he wanted to train him but the jedi council wouldn't allow this because he already had a padawan, Obi-Wan Kenobi.
1 Anakin Never Was Punished
At most, they would scold him for his behavior. The Jedi Council was too passive when it came to Anakin's education, and it fostered a toxic relationship with him. He knew that they did not trust or approve of him, and as a result, he lost trust in the Council.
Anakin was already too old to begin Jedi training as he was not brought to the order until he was nine years old. He had already formed a strong attachment to his mother, and attachment is forbidden among the monk-like Jedi.
According to the Episode III novel, Windu believed that Anakin's powers were growing far too quickly, and that he was not disciplined enough to control them. "Skywalker is arguably the most powerful Jedi alive, and he is still getting stronger.
Good question! First and foremost, Obi-Wan didn't want to have to confront and try to kill Anakin, we see this all the way until their final conflict in their duel where Obi-Wan pleads with Anakin to not make him do what he knows he'll have to do if Anakin tries to attack from the low-ground.
Anakin admits to Obi-Wan that he has been arrogant and unappreciative of his training, and apologizes to his master. Obi-Wan assures Anakin that he is proud of him, telling him that he has become a "far greater Jedi than I could ever hope to be."
For years, Vader hated Obi-Wan, having been struck down by his mentor and left for dead while also believing the Jedi had worked to turn his true love Padmé against him.
This is the most well-known of the Jedi rules. Love leads to attachment and attachment leads to strong emotions, which are the path to the Dark Side of the Force. Because of this, Jedi are forbidden to fall in love. This, of course, doesn't stop Anakin Skywalker from falling in love with Padmé.
Master Yoda failed Anakin Skywalker in Star Wars: Episode II — Attack of the Clones, and it resulted in the destruction of the Jedi Order. Master Yoda is one of the most revered characters in the Star Wars universe, and for good reason, but he ultimately failed in stopping the rise of the Sith.
We go for the more simple answer, further considering the details of the question itself. If Anakin didn't go into that chamber as the Jedi confronted Palpatine, then Mace Windu would have defeated Palpatine, killing him.
Anakin does not have even the slightest bit of remorse. By the end, he feels nothing but anger. Although he feels regret for killing Padme, he still helps the evil Emperor. The film ends with Anakins standing side by side with the man on whose behalf he has committed all his crimes.
The canonical comic Star Wars: Darth Vader #7 confirms the younglings' deaths caused Anakin grief, self-loathing, hatred and pain, fueling his descent even further into the dark side.
Although the decision to turn to the Dark Side was Anakin's alone, the choice did not come from thin air. His natural prone to impulsivity and emotion without the support systems he needed in place made it easier for Anakin to stumble down a path of darkness.
Padmé was repulsed, and with the appearance of Obi-Wan (who had stowed away on her ship), Anakin assumed his wife had betrayed him, and he Force choked her.
Presumably Palpatine planned to have Anakin join him at that point and so told the clones not to kill him when he gave out Order 66.
The Jedi prophecy foretold the destruction of the Sith, but it never predicted the end of darkness. Although Anakin Skywalker brought the Force back into balance, the Jedi Order was decimated by his actions as Darth Vader, leaving Luke Skywalker as the last of the Jedi.
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: The Phantom Menace.
The Jedi from the Star Wars prequels, including Master Yoda, did not understand Anakin Skywalker's Chosen One prophecy for these essential reasons. The Jedi of the Star Wars prequel era clearly did not understand the famous Chosen One prophecy.
Though he saw Anakin's potential, Yoda could not ignore the danger inherent in Anakin's unrestrained emotional attachments. To teach Anakin responsibility, Yoda assigned Skywalker a Padawan learner: Ahsoka Tano. Yoda knew there would come a time when Anakin had to let go of Ahsoka.
What Padmé knew about Anakin's previous dark deeds. Padmé was well aware that Anakin had committed dark crimes that would've started his fall to the dark side. He even confessed to her that he had massacred an entire Tusken Raider village to avenge his mother, leaving no one alive.
Had Anakin not converted: Padme would have been killed by the Emperor before childbirth, and before Anakin and Obi wan returned from the mission to destroy general Grievous. Regardless: order 66 probably still would have happened since the army was under control of the dicator in Palpatine.
However, when they next met in Star Wars: Episode II – Attack of the Clones, Anakin and Padmé's feelings for one another grew into something resembling love, and their wedding at the end of the film solidified their relationship as one of the most important romances in Star Wars history.
Did Darth Vader ever regret killing Obi-Wan Kenobi in Canon or EU? He does. Right at the end. With Luke crying over him and Vader sensing his anguish and pain he had inflicted on all those who had cared for him.
It is unclear whether Yoda would be more or less forgiving than Obi-Wan but one thing is certain - the former Grand Master would be ready to treat Anakin as an ally, following the events on the second Death Star. In Star Wars: Revenge of the Sith (2005), Yoda never really lost faith in Anakin in the way Obi-Wan did.
He slays Sidious and returns to Obi-Wan, begging for atonement by execution, only to be met with true forgiveness instead. But just as this fantasy Obi-Wan refuses to strike his former friend down, Vader refuses to turn his back on the dark.
