This way it would be Palpatine pushing Anakin toward the Dark Side rather than Padmé seeing nothing wrong with slaughtering children. Palpatine being the only one who knows what Anakin did to the Tuskens would explain why Padmé didn’t see his turn coming.
Yes, Palpatine would have been a better choice for the line. But given the way the so called romance or love story was written in AOTC it is doubtful even this line could have saved or made it less “icky”, toxic, controlling or abusive.
Maybe Anakin instead could have said:
“Please don’t look at me like that.
Palaptine : Why not?
Anakin : Because it makes me feel uncomfortable”
and gone on from there. It would have made more sense!
Anakin about Padme in her sleeping quarters: “She covered the cameras. I don’t think she liked me watching her.” She is obviously uncomfortable with Anakin watching her, again.
Anakin later blames Padme for “the kiss that you should never have given me”, despite it Anakin being the person to instigate that kiss, before Padme quickly put a stop to his advances.
Anakin to Padme: “I… I killed them. I killed them all. They’re dead… every single one of them. And not just the men. But the women… and the children, too. They’re like animals, and I slaughtered them like animals! I HATE THEM!”
There is obviously a lot more to this, from Anakin disrespecting Padme’s authority as a person, and openly undermining her authority in front of others. She repeatedly tells him to stop making advances and he refuses to accept these requests. Even Anakin outright telling Padme he doesn’t like what she does, or stands for, and that a dictatorship is the correct way to run a galaxy.
But on Geonosis this all changes, Padme professes her love for Anakin, which is pretty much out of nowhere (other than George’s fetish leather scene in front the fire), and they marry in secret soon afterwards. Huh. WTF?!
Yet all of the above is portrayed as some sort of this is all a part of a “will-they-won’t-they” fall in love scenario, but in reality it comes across as toxic and controlling. The toxic and controlling aspects would have been better served on screen demonstrating Palpatine and Anakin’s relationship, and Palpatine’s growing influence and control over Anakin - not in Anakin and Padme’s poorly written and unbelievable “love story”.
