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?
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.
If you are asking about Vader post-Mustafar, then no, she doesn't. Padmé doesn't seem to know Obi-wan cut off his limbs and left him to burn alive, Obi-wan didn't believe Anakin to be alive and Anakin's surgeries were still happening as Padmé died so there was no way for her to know.
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.
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. To Anakin, he tried to rationalize he had no choice.
Darth Vader awakens, and his first question is about the whereabouts of Padmé. 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.
Darth Vader was aware that Padmé Amidala died. That's because Palpatine told him what happened to Padmé after he saved Anakin on Mustafar. In fact, there was a big funeral held for Padmé on Naboo. But Vader didn't know that Padmé died of a broken heart as he thought she died by his hand.
Short answer: no. Her little run-through with Clovis was during her early Senatorial days, before Anakin came along and fell head-over-heels in love with her. Any feelings she exhibited for the former on Scipio were purely out of respect or for business (since he was a powerful member of the Banking Clan).
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.
She knew he was volatile and even murderous after he slaughtered the Tusken Raiders. As such, the only reasonable explanation for her marrying Anakin is that she was truly in love with him.
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.
However, when Palpatine destroyed the Republic, Panaka sided with him. Though he never acted against Padme, his support of Palpatine included the support of a stronger military presence, which was a betrayal of her ideals.
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.
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.
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.
In Star Wars canon, there are currently only four younglings that are known to have survived the infamous Order 66 and Darth Vader's slaughter, while in Legends, there are 20 known survivors.
As Padmé grows more and more visibly pregnant, why did no one wonder who the father was? Rush Clovis is really the only possible answer. The timeline matches up pretty well, and their prior relationship was common knowledge.
Ultimately showing the darker side of Anakin's love, his passionate nature leads him to care for Padme with all of his heart, far in excess of anything else in his life.
Padmé was born in 46 BBY (Before the Battle of Yavin) and Anakin's miraculous Force-created birth came in 41 BBY, so Padmé is five years older than him. They do not meet until Star Wars: Episode I - The Phantom Menace, which takes place in 32 BBY.
Padmé was just a friend. It's only the way he talks about her around Leia that could make one wonder if he harbored feelings for the Queen and Senator from Naboo.
Since he was a kid, Anakin showed greats amounts of obsession. This obsession, of course, leads to him turning to the dark side of the Force years later. There are some fans who strongly believe that Anakin used the Jedi mind trick ability to seduce Senator Amidala, and made her fall in love with him.
Despite their growing attraction, Amidala did not believe that she could be with her Jedi protector; Amidala was a prominent senator, and Skywalker was required to follow the Jedi Code, which forbid attachments like romance.
Anakin Skywalker never knew Padmé was pregnant with twins, and he believed his child had died with his wife. He had no idea Padmé had given birth before she died, still less that the Jedi had spirited the children away and hidden them.
It then becomes feasible that Padme felt she fulfilled her purpose by giving birth to her children, consequently losing the will to live. However, that theory takes a bit of a hit from the fact that she claimed there was still good in Anakin, thus work to be done before her death.
and Learned that Padme had died, he screamed in anguish. and crushed all of the medical droids around him. Vader targeted Palpatine next, unleashing his rage upon his new master, sending him flying backwards into the wall.
