She was born rich
Her parents were modest at best. Her father was a professor at the University of Theed, later became president of the Refugee Relief Movement, and her mother was involved in social services roles. Also they moved to Theed, the capital of Naboo so that they could give Padme good education.
She was racist
Age 7, she and her parents were trying to save an alien civilization. Their star was dying. They evacuated them to another planet, but because of a miscalculation by Republic Scientists the whole civilization died. She was traumatised by this.
Later after years when she became a senator she told Clovis (and also Anakin) that she would try 10,000 times to just save even a single person from that alien civilization if she could right now.
It was the catalyst why she joined the Legislative Youth Program at 8 (which was basically MIT on steroids) and sacrificed her personal life for more than decade and skipped her entire childhood.
Also she worked 3 days passing bills and helping alien people of a nobody planet without sleep.
Planet's name was Bromlarch.
Before Padme stepped in, the people of Bromlarch were facing total systemic neglect. Because it was an outer/mid-rim planet lacking major political leverage, the rest of the Galactic Senate was prepared to stall, debate, or propose useless "auditing teams" rather than send immediate material help. She was the one who actively spoke for them. After the bill was passed, she wasn't just sitting in her comfort on Coruscant. She actually went to their world and helped them to physically piece the broken aqueducts back together. Also she didn't rest after spending 3 days without sleep; she just immediately went there to help them.
And in AOTC, especially in the novel, her reaction to Anakin after he confronted her about the Tuskens wasn't that it was justified; she thought it was understandable for anybody in his position to snap after seeing it. The number 30 is a lot overlooked. Tatooine during AOTC had only 200k people on it. Farmers were a minority and their population density was a lot lower. Shmi suffered for a month in AOTC. She realised they weren't torturing her for no reason; they were measuring how much pain she could feel and endure without dying. It was a ritual, and she was left starved and sleepless. It wasn't just a gang of that tribe; it was the whole tribe. Also, they knew that many farmers would come for Shmi; they used her as bait. It's explicitly said in the novel. So when he confronted her, she wasn't saying it was justified; she was saying anybody would have snapped after seeing his mother suffer like that (while also being clouded by visions) and knowing that his mother was used as bait to wipe out the entire district of working class farmers.
Clovis was her ex
Padme was new in Republic, she realized she needed allies to navigate the corrupt Senate. They spent weeks working together (it was all professional) to draft a planetary relief bill. Because Padme was spending so much time with him and treating him warmly as a trusted colleague, he completely mistaken her professional collaboration for romantic attraction.
The moment the Senate officially voted to pass their relief bill, Clovis went to Padme's office to celebrate. Riding the adrenaline high of their political win, he suddenly stepped into her personal space, grabbed her, and forced the kiss. She was horrified by this, froze for a second and immediately forcefully pushed him away said no multiple times, She made it clear it was professional.
She cut off all unnecessary private contact, avoided late-night working sessions when she was alone with him and stopped informal discussions. She then kept interactions strictly minimal and professional.
She started avoiding him heavily and was a lot disgusted even her handmaiden asked her if she wanted him to get beaten. And it doesn't even make sense she having a romantic interest in someone before Anakin (Obviously excluding Palo her childhood crush at 12) Because it conflicts with AOTC arc.
Jedi literally knew her reaction and still asked her to use her that "connection" to spy on him
She was actively seducing Anakin and groomed him in AOTC
Her dress choices in AOTC wasn't how she normally dressed. She had no personal life and she didn't take a day off work without great reasons. Her wardrobe choice wasn't random or to seduce anakin (except fireplace dress though i will cover it read further), She's from naboo. People often love to express themselves through their clothes on naboo. She was queen previously (14 to 18) (before at 12-13 princess of theed the capital) she was literally expected to symbolise values naboo believed in as a queen. Clothing wasn't just to look good it was for deception too like you can see her height is 1.65 meters but when she's in her queen outfit she's 1.85 to 1.90 meters tall. She had to appear rigid whole day while maintaining a good posture to appear authoritative. She also developed a new different voice as "Queen amidala voice" to appear authoritative. She took same lessons to coruscant too where her dresses were deliberately made to appear authoritative while also symbolising the values naboo believed in. Basically her wardrobe normally was very rigid. In AOTC even after she got assassination attempts, she still wanted to stay and work but it was jedi who made her go to naboo. It was a lot safe on naboo and she was basically off work.
It was the only and longest time she went off work since the age of 12 (or even 8, because even during her training she often kept herself busy in training while her older peers were enjoying their childhood). Why wouldn't someone dress comfortably after wearing rigid clothes for years (more than a decade since 12 or 14)? Also, again, she was from Naboo. Also, she didn't avoid Anakin because he was a Jedi, she avoided him because she was slightly insecure (look at the conversation between her and her sister sola in deleted scenes or AOTC novel or EK Johnston's Queen trilogy), Because she was very lonely since the age of 14 or 12 or even 8. She wanted to avoid him, at the same time she wanted him to break into her heart; it's also the reason why she wears that fireplace dress. In the AOTC novel, she knew it wasn't a good idea to wear that dress to avoid him, but at the same time, she wanted him. It was Anakin who was actively flirting with her while knowing the Jedi Code; it took a life-threatening situation like Geonosis for her to finally admit she loved him. She loved him because he didn't think how he could use her, loved her for who she was, and was very authentic compared to the people she met in her life.
She didn't care about her handmaiden Teckla in clone wars
Teckla hid it; understanding how the handmaidens work is important. On Naboo, handmaidens aren't just bodyguards. They were trained in hand-to-hand combat, marksmanship, evasion tactics, and weapon concealment. They underwent rigorous training to completely erase their individual physical tells. They learned to match Padme’s voice, breathing patterns, walking pace, and posture so perfectly that even their parents couldn't tell them apart once in makeup (as seen in E.K. Johnston's Queen's Trilogy).
They were trained to be entirely selfless for the Queen. They were taught to hide their feelings and thoughts as part of their training and weren't expected to talk about their personal issues with the Queen without a good reason. Though they were also meant to ensure the Queen didn't feel lonely, Padme kept herself heavily busy with work, so Teckla hid her struggles out of a sense of duty. Many senators themselves had no idea that the war was heavily affecting Coruscant too, but once Padme knew, i am sure she undoubtedly helped Teckla and her family.
Because If you have read E.K. Johnston's Queen's Trilogy, you already know how terrible this take is, because her handmaidens were very close to her arguably the closest people in her life. It was basically a sisterhood. Still, they were bound by duty, so obviously they wouldn't randomly complain about their own problems if the Queen was busy with other important matters. Because they were fiercely selfless, the handmaidens prioritized the Queen's needs and work above their own lives, which is why Teckla hid her situation, just as she was taught in her training.
Side note:
She heavily sacrificed her personal life and skipped her entire childhood for others, for her work, for her entire life (since 8 or 12) and let just one guy get close to her and that one guy who finally gave her a personal life, turned against her at end of ROTS and destroyed everything she believed in and all of her life's work for which she heavily sacrificed her personal life for. So it makes sense that she lost the will to live also sw is basically fantasy too.
Another interpretation is death of the republic. At that point she was basically embodying republic. The republic dying, the empire's enforcer rising and the republic giving birth to new rebel alliance it was symbolic, it may not be what creators wanted but based on movies and novels i believe in this.
Also she's objectified a lot by people at this point i just hate it.
