Yes, he did. He regretted it everyday. But he had no choice.
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.
Did Anakin ever regret becoming Darth Vader? Yes he did. And the saddest thing is that there was nothing he could do about it.
Anakin Was Meant To Destroy the Jedi Order
Although, if Anakin's prophesy was fulfilled, it suggests that his turn to the dark side was meant to happen all along. If Anakin had killed Palpatine in Star Wars: Revenge of the Sith, then the Jedi would see the prophecy as fulfilled.
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.
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.
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. Those negative emotions also power the dark side, meaning Anakin likely felt stronger as he killed the younglings.
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.
During the battle, Anakin, who had been known as the Sith Lord Darth Vader, was redeemed by Luke and brought balance to the Force. However, the redemption cost Anakin his life, having been mortally wounded by the Emperor, Darth Sidious, while killing his former Master. After his death, Anakin became one with the Force.
The Jedi Council's Rules on Attachments
The choice to leave his mother at a young age continues to haunt Anakin throughout his life. 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.
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."
Can't Stand - Emperor Palpatine. Some would say that Palpatine represented Vader's only friend and companion, but real fans know that this is anything but the case. In many ways, Palpatine enslaved Vader and, over the years, Vader undoubtedly grew to resent his master.
The Jedi, with the exception of Obi Wan (and Qui Gon before he died), openly distrusted and even disliked Anakin.
Mace completely dismisses him as not just the Chosen One but also a Jedi. He seems particularly spiteful towards Ahsoka, especially when the last time the two interacted, he brushes off as a citizen. Then, he blantantly admits to not trust Anakin.
Absolutely, had Anakin wanted to be redeemed. Obi-Wan looked at Anakin as a brother, and even before their final battle, Kenobi: Lied to the Jedi Order, or at the very least lied through omission and silence about Anakin's romance with a prominent anti-war sentator.
They have a grudge against each other because, well, let's face. Mace Windu was not pleased to see Anakin at the Jedi Council Chambers in The Phantom Menace. He disliked the idea of letting a young boy join the order. And from then on, he never exactly created a bond with Anakin Skywalker.
Not even by Luke. Luke gave him unconditional love, but that's not forgiveness. Anakin, as Darth Vader, committed and was complicit in a whole bunch of genocides and other crimes.
Short answer? No. It's been clear that the main issue had to do with Anakin's mental state. If Anakin just got the help he needed and stayed loyal to the Jedi Order, overcoming Palpatine's evil temptations, Padmé would've survived.
At least partially, Padmé is experiencing a kind of Stockholm Syndrome or more specifically, the idea of equating affection with crime, a disorder known as hybristophilia.
Did Padme ever cheat on Anakin? No. As explained above, Padme did not cheat on Anakin with either Obi-Wan Kenobi or Rush Clovis.
No she didn't regret marrying him. She regretting not being able to save him. She still loved him, still believed (RIGHTFULLY) that he would return.
In the duel, Anakin lost both of his legs, his one remaining organic arm, and suffered (possibly up to) fourth-degree burns across what was left of his body that were severe enough to damage his internal organs.
Anakin Got His Scar From Dooku's Apprentice, Asajj Ventress
Ventress, one of Dooku's deadliest assassins, seeks to kill Vos for his actions, however, she is unable to get to him. Instead, she settles for a Jedi she can find: Anakin Skywalker.
Early on, they realized that Anakin Skywalker was filled with fear and had little control over his emotions, so they were hesitant in training him to be a Jedi. However, they allowed it to happen.
