He still believed Palpatine was telling the truth when he said he would help save Padme. So, from Vader's distorted point of view, Palpatine had done nothing wrong and was the only person left by his side. And rather than lose everyone in his life, he figured he might as well commit to his life as a Sith.
Thus, he never had any romantic relationships again after Padme's death. Even if he wanted to, I highly doubt he could have after all the injuries he sustained on Mustafar, anyway. If this were real life, he would have died on Mustafar after Obi-Wan chopped off his limbs and left him to burn alive.
It's clear that Darth Vader wishes that Padmé joined him so that they could have remained together. But there are moments in Marvel's other Darth Vader series that suggest that, while the Sith Lord is very much still obsessed with the idea of Padmé, her betrayal may have caused him to think ill of his late wife.
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.
George Lucas Explains Why Vader Stayed Loyal to Palpatine After Padme's Death
Would Padmé still be alive if Anakin didn't turn?
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.
Anakin's vision did come true, as Padmé, heartbroken by her husband's downfall, loses her will to live and succumbs while giving birth to twins. Before her death, Padmé still believed there was still good left in Anakin and that one day he could be saved with the help of their children.
Anakin's Force Choke begins the series of injuries that ultimately leads to Padme's death, and convinces Obi-Wan to fight him. Despite this, when Anakin learns of Padme's death, his immediate reaction of grief and regret shatters everything in the lab with a powerful force shockwave.
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.
After Darth Vader refused to kill both Luke Skywalker and Padmé's body double, Sabé (which would've threatened his manipulation of him), Palpatine punished him by attacking him with Force Lightning.
According to series creator George Lucas, the power loss resulting from Anakin's injuries is what drove Palpatine to decide to replace his apprentice with Luke. "Anakin, as Skywalker, as a human being, was going to be extremely powerful,"Lucas explained in 2005.
Palpatine tells Darth Vader that in his anger he killed her, placing the blame for Padmé's death on Vader. Vader denies it, saying he sensed Padmé was still alive, which the audience knows she was as Obi-Wan escaped on the ship with her.
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.
Padme Amidala's secret marriage with Anakin Skywalker was one of the biggest reasons he eventually turned to the dark side. His emotions and love for her often clouded his judgment, and sometimes led him to be violent.
Before he could enter, however, Vader was stopped by Sabé, Eirtaé, Rabé, Saché, and Dormé, former handmaidens of Amidala, who refused to let him enter into the grave so he would not desecrate it. However, Vader would not be denied. As he entered the tomb, he became flooded with memories of Amidala.
And he's already murdered Mace Windu at Palpatine's behest, more or less by stabbing the Jedi in the back. 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.
When Anakin had to choose between losing Padme — fearing that she might die in childbirth — or turning to evil to “save” her from death, he chose evil. His desire to “save” her at all costs led Anakin to the dark side. For him, the dark side became a means of saving his loved one.
Ironically, it was Anakin's desperation to prevent Padmé's death in Revenge of the Sith that led him down the path of destruction that would result in him bringing that very death to fruition. Consequently, Anakin — now the Sith Lord, Darth Vader — lost Padmé when he was just 22 years old.
Miraj Scintel, the Zygerrian Queen was an incredibly powerful woman who ruled the slave industry galaxywide. She invited Anakin for a visit and let me tell you the tension was HIGH. Then, Anakin whispers something in her ear that we don't hear, and she went all *bonk* for Anakin. Thankfully, he did not cheat on Padme…
Why didn't Obi-Wan say anything about Anakin and Padmé?
He fell in love with Satine and would have left the Jedi had she asked him to, but she did not, and so they parted ways, divided by their duty. Obi-Wan couldn't help wishing Anakin the happiness he had been denied, and therefore, he decided to keep the marriage between Padmé and Anakin a secret.
The dark times. Naboo was in a state of mourning for Padmé Amidala, who died following the rise of the Galactic Empire. Following the rise of the Galactic Empire and Palpatine's self-proclamation as Emperor, Naboo hosted one of the new regime's military garrisons.
Dooku, AND Anakin, would be less likely to fall to the dark side if Qui-Gon was left alive and Maul's sympathetic past would never be revealed. For the former, Order 66 wouldn't be executed since Dooku wouldn't be the one planning to do that on the clones.
