These days I'm seeing quite a lot of "Satine was fridged for Obi-Wan's character development", and claims that she was created only for him and didn't have any other function in the story than showing a new side of his character. Also, apparently she was created to show HOW MUCH BETTER Obi-Wan than Anakin was regarding their respective relationship with Satine and Padme.
First I think that this last point is very debatable. If you take the time to analyze the facts we have, I don't think it's that clear cut 🤨
Second and more important, Satine was an IMPORTANT character in TCW outside of her relationship with Obi-Wan. And if anything she didn't die for the sake of Obi-Wan's character development (is the character development in the room with us?), but for her sister's Bo Katan.
In this post, I know it's not typical but I will develop the second point only.
Satine wasn't introduced in the show as Obi-Wan's ex girlfriend. Actually, it's only through crumbs of conversations with Anakin and then during Satine's love confessions that we could understand that a long time ago, they were lovers.
Satine was introduced as a pacifist and as a fearless and stubborn LEADER, a woman of principles who refused to side with the Republic or with the Separatists in the war. In the context of that time, this alone made her a singular figure, someone whose life was constantly at risk because Mandalore was an important system that each party wanted on their side. Satine was an inconvenience, hence why Dooku approached Death Watch, who wanted her dead (and yes that included her sister Bo, even if we didn't know she was Satine's sister then, it doesn't change that fact), and why Palpatine pulled strings in the dark to make her death happen as well.
It's the same reason why he tried to get Padme killed multiple times as well: her death is too unfairly reduced as Palpatine's plan to make Anakin fall only, while he had political, more important reasons to want Padme dead too.
These women had voices, they had influence, and they kept speaking words Palpatine hated to hear because other leaders in the Galaxy listened to them. Satine and Padme HAD to be out of the way, one way or another. So when you say, "Satine and Padme's arcs revolved entirely around men, they were created only to further their development, nothing else, and they were killed only so these men would be sad", it hurts my feelings a bit.
And now regarding Satine's death. I struggle very much with the concept of her being "fridged" to further Obi-Wan's development, considering that her life was threatened since season 2, and for reasons that were totally unrelated to her connection with Kenobi. Satine's murder was planned by Pre Viszla along with Maul's and Savage's. She would likely be dead now, with or without her romance with Obi-Wan, because she couldn't be alive for what would come next in Mandalore.
The only "fridging" part I could agree on is that Maul realized that Satine was important to Obi-Wan, so he used her as bait and killed her for the sole purpose of hurting him. But Satine's death didn't impact only Obi-Wan, who before season 7 referred to her only once when he lectured Anakin about attachment. Then in season 7, he was basically forced to do so by Bo Katan.
Don't get me wrong, I think it would have been very OOC for Obi-Wan to openly cry over Satine's death, to be visibly depressed etc. Obi-Wan would never: his thing was always to repress his feelings. I like to think that the Council forced him to "rest and meditate" for a few days, but that Obi-Wan's only wish after her death was to come back to the battlefield so he could mindlessly destroy some droids and avoid any thoughts that could have him spiralling.
My point here is that as far as Obi-Wan's character development is concerned, I just don't see what Satine's death did in this regards, but maybe I'm dumb? Yes, he was devastated by her death, but she's not the reason why he was a mess after Revenge of the Siths. Anakin's fall was. I don't think he moved on from Satine's death as easily as it looks, but it didn't change him, and it didn't break him either. In the Obi-Wan show, she's not even mentioned once, by him or anyone else.
In terms of character development, it was Bo's who was the most impacted by Satine's death. About that: I think the writing was very clumsy and I still resent her for yelling at Obi-Wan in season 7 while she was very much okay with murdering her sister when it was her boyfriend who ordered it; Imo TCW did a very poor job at showing her dealing with the fact that Satine died in great part because of her and her actions.
But then Rebels happened. There, we saw Bo reflect on her past actions, and we saw how remorseful she still was. I'm still not her biggest fan. I still find her character inconsistent, especially since Mando season 3. And I hate how Favreau couldn't bother to name-drop Satine in a show about MANDALORIANS, even though she was an important figure in Mandalorian history, and was the sister of the woman whose dream is to unite the clans and to make Mandalore great again.
Anyway, I'm not looking for a fight, I just think it's wrong to say that Satine was only killed to further a man's arc, while her death not only impacted a female character's too, but Mandalore's political landscape as well! With her out of the way to promote her pacifist idealism, Mandalore returned to what it was before she took the reins, and even after Maul left, no one managed to unite the clans. Then the Empire took over and the rest is history. Her death was impactful for the plot, and difficult to avoid.
But Satine Kryze existed only for Obi-Wan to have a girlfriend and to be sad when she died, I guess.
