He didn't know how to save her, and never would have learned. All of that Darth Plagueis mumbo jumbo was a carefully worded trick Palpatine used to lure Anakin to the Dark Side. Even if Plagueis really could do that, he never taught it to Sheeve.
In the main Star Wars timeline, of course, Darth Vader's attempts to resurrect Padmé on Mustafar were doomed to failure. But it's fascinating to speculate what would have happened had he been successful. In that scenario, Padmé Amidala's return from the dead would not have provided the solace Darth Vader sought.
Palpatine knew the dark side could save him from death, and he was able to “cheat it”. He probably could have saved Padme.
So overall, it seems highly likely that the answer is no, Palpatine didn't have the power to save Padmé's life. He hadn't even begun learning the power when Anakin became Darth Vader, and the idea of saving lives was of no interest to him.
Yes, his entire character since then was a self loathing tragic monster who has little reason to care about anything. Betraying Mace Windu instantly made him regret his act of impulse, Padme's death and rejection of his actions later on made it stick.
It's not shown, but it is clearly insinuated that Anakin killed the younglings. This is confirmed later in the movie when Obi-Wan informs Padme that Anakin killed them. Both are torn apart with hurt and confusion, trying to make sense of something so terrible. How could Anakin do such a thing?
Originally Answered: After Padme died why did Anakin choose to stay on the dark side? The only reason why Anakin joined the dark side in the first place was to save Padme from dying during her pregnancy. He had no choice after the events of Episode III. He had lost his wife and his friends/comrades in the Jedi Order.
While Force healing could have saved Padmé, material from both continuities explains why Anakin couldn't use it. The Force is a fundamental omnipresent energy that can be used as “powers” by those who are trained to tap into it. One such power is healing oneself or another at an enhanced speed.
Padme's death was just too convenient for Palpatine to prevent. Her death is the final nail in Anakin's coffin. Besides, she knew too much about Palpatine's true nature and would've used her position to oppose him. Originally Answered: Did Emperor Palpatine actually have the ability to save Padmé from death?
Palpatine seduced Anakin by promising he could save Padmé using the dark side of the Force. But in the end, he lied that she was killed by Anakin by mistake.
Sadly the Clone Wars would have still happened, but Padmé would have also survived, giving birth to Luke and Leia who would have probably been inducted into the Jedi Order. As for what would have happened between the two, with their marriage and all, that's a bit tricky.
Star Wars has revealed Palpatine wasn't lying when he claimed he could have saved Padmé's life, adding even more tragedy to Revenge of the Sith. A new Star Wars book has revealed Palpatine wasn't lying when he described Darth Plagueis' abilities to Anakin Skywalker in Star Wars: Episode III - Revenge of the Sith.
Anakin would have likely been killed by the clone troopers, along with the other Jedi. However, perhaps he would have escaped. He would have taken the pregnant Padme with him. He would have needed to get as far away from the eventual Empire as possible, so perhaps they would have gone with Yoda to Dagobah?
Padme's death is the moment that solidifies Darth Vader's fall to the Dark Side, and expanded Star Wars media has often shown him mourning her when not serving The Empire.
There's a pretty good chance that Padme would have lived if Anakin had not fallen to the Dark Side of the Force. One of the big reasons is that, in storytelling, especially mythic storytelling, it's very common for prophecies to become self-fulfilling.
The film doesn't flinch away from how horrific that act is, especially as it begins the downward spiral of Padme's death. Nonetheless, as she dies, Padme tells Obi-Wan that there is still good in Anakin. Even something as heinous as that couldn't fully break her love for Anakin.
With Chancellor Palpatine's death, the de facto "Prime Minister" of the Republic, the Senate would be left without a leader and there would be considerable political confusion and chaos. There would be a need to elect a new chancellor to lead the democratic government.
But the twist was that Palpatine lied to him by telling him a different story. The emperor told Vader that Padmé died due to Vader's rage when he used the Force to choke her, as the former Anakin couldn't believe it because he felt that she was alive before he released his hold over her.
It was also part of Darth Sidious' plot to ensure the passing of the Military Creation Act, of which Amidala was one of the leading opponents. The first attempt initially appeared to be a success, but Senator Amidala was found alive. The second attempt, however, was foiled by Jedi Obi-Wan Kenobi and Anakin Skywalker.
His only reason for turning to the dark side was a need to protect the ones he loved and to learn the secrets of preventing death. From Anakin's point of view, becoming Palpatine's apprentice was simply a way of becoming more powerful, and all the evil tasks he had to complete were to bring him closer to his goal.
He loved Padme but hated what he thought she just did. Being the low-wisdom guy that he was, he acted on his hatred immediately as Palapine encouraged him to do. He couldn't force-choke Obi-Wan (the one he really wanted to do it to), so he did it to Padme (the one he could do it to).
The story is Anakin was manipulated to the dark side by Palpatine based on fears of losing Padme and appeals to his desire power and agency, over his life and the galaxy as a whole.
Giving in to his feelings, Anakin cuts off Mace Windu's hand, giving Palpatine the opportunity to kill him. Anakin regrets this almost instantly, but the thought of Padme was stronger than his remorse This is the moment Anakin officially became Darth Vader and led to serious issues in the Skywalker Saga.
The Younglings Reminded Anakin of How Different He Was
Those negative emotions also power the dark side, meaning Anakin likely felt stronger as he killed the younglings. That, in turn, reinforced his belief that only the dark side could save Padmé.
He is plagued by nightmares of her and visions of her fate. When he eventually saves her from a group of Tuskens on Tatooine, his blind anger at her dying state consumes him. Focused on revenge as he murders an entire Indigenous tribe, Anakin has begun the path to the Dark Side.
