So I’ve been thinking a lot about Obi-Wan thinking Anakin was irredeemable, and it’s significance to both narrative and character. Obviously it’s indicative of his Jedi roots, but there’s more than that. It’s a contrast to Padme and Luke, and aligns him, oddly enough, with Leia. And another thing these two have in common is that they’re military leaders - actual Generals, who fight in actual wars, rather than a Senator and a farm-boy turned rebel pilot, both of whom do have experience with combat zones but unquestionably to a lesser degree. Anyways, it doesn’t seem coincidental.
Obi-Wan and Leia are more often exposed to the cost of warfare, and for prolonged periods of time. (You could say they’re overexposed, that they’re saturated in it.) There’s no question in war that you will see your men fall on the battlefield. (And there’s no question that your loved ones will disappoint you, especially in hard times.) When you get shot in the company of somebody like Leia or Obi-Wan, they’re focused on the fact that the enemy is closing in and the other men will still need a leader tomorrow. Every battle has casualties. Generals can’t afford to go back and take your pulse; there’s no point.
But when you get shot in the company of somebody like Luke or Padme, they focus on the fact that you’re still breathing. They want to save you. They still think they can.
First instinct might be to look at the way that people like Leia and Obi-Wan think and be unnerved, but this clearly is not the result of some moral failing on their parts. It’s different from the detached, unfeeling calculations of institutional leaders like those in the Senate dealing in hypothetical battles and economic equations, or even those on the Council who never commanded troops. Those leaders get to indulge in a degree of separation between the issuing of orders, untouched from a distance, and the actual execution of them. (Not to mention that many in the Republic treat clones as weapons rather than soldiers.)
No, Leia and Obi-Wan don’t operate the same way. It’s different, because they have to decide how their men will risk their lives. Then, during the battle, if they have to retreat, or push forward, or change course, they have to decide who to leave behind. That isn’t to say they won’t try to save all they can. There will be guilt for those they can’t save (you can see Kenobi’s guilt on Mustafar for his inability to bring Anakin back as well). But commanders understand that the future depends on soldiers that can fight. This is the survival mode that people lapse into after being charged with the responsibility of military leadership. It’s a survival mode which requires one take on the care of a cause, and an army, not just oneself.
Luke and Padme have experience with the military to a certain extent (Padme more so than Luke in this regard) but they aren’t ever responsible for what happens on the battlefield, who dies and who lives. Padme has the small amount of control that being a Senator and a diplomat grants her, but again, this is different from being a military commander. Even Luke’s direct military involvement, throughout the series, is kept to being a pilot, and an independent operative, at least as far as I’m aware, and if we keep to the span of the OT. They had happy enough childhoods, with little to no impact from their respective trilogy’s wars, as Padme was an adult by the time the Clone Wars began, and Luke’s residence on Tatooine in the Outer Rim was the least of the Rebellion’s, and I’m sure, the Empire’s concerns.
In the face of Luke and Padme, and Leia and Obi-Wan, Anakin is an outlier, which aligns with his role as the one who falls rather than the one who reacts. His situation is much closer to Leia and Obi-Wan’s, but in the face of multiple battles and the exile of Ahsoka, he doesn’t exactly show that same mentality. Sure, he’s an important leader who understood the costs of war and acted rationally (as far as he goes) in handling them. But, despite being a general, he never seemed to truly adopt that military mentality of “you can’t save them all” - he literally falls in his attempt to save his family’s lives. And I’d be willing to argue that this is largely because, unlike Obi-Wan, and unlike Leia, Anakin entered the war with a survival mode already installed - that of a child slave.
Speaking of Anakin’s military history and its affect on his character, it also offers a different lense through which to analyse Obi-Wan’s infamous “certain point of view”. After all, Anakin dying a young, Jedi war hero was, at one point, a real possibility. How does this interact with his real-life fall to the Dark Side? Well, you could claim that in both versions, Anakin was a casualty of war and institutional corruption. After all, it was Palpatine who orchestrated both environments, and in both versions, the Jedi Order failed to save him - does it matter much (outside of the OT) if he fell in combat during the war or to the Dark Side after?
It is interesting also to examine Obi-Wan’s claim that it was Vader who killed Anakin. The meaning in this is obvious - it’s discussed outright in the OT. There’s no need to go over it. However, it does hold implications, upon further inspection, to something crucial in Obi-Wan’s perspective about his former padawan’s fall. Anakin, as Obi-Wan knew and cared for him, was dead, and while Darth Vader may have finished him off, is it so unreasonable to suggest that it was General Skywalker who had chipped away at him for so many years? This is a metaphor that Kenobi could never have used with young Luke, for obvious reasons, but it is, if nothing else, something to contemplate further. Did Obi-Wan consider Anakin’s fall a decline or a sudden drop? Did he consider it inevitable or did he factor in the stresses of the war? Of dealing with Jedi culture? Of being born into slavery?
It’s so easy to forget, in the context of the films, and what we’re shown, that Anakin and Leia were generals before reaching their twenties, that Ahsoka Tano was taken from her home and raised a child soldier, that Obi-Wan was tasked with the responsibility of raising a child that he later had to watch be turned into a weapon for the powerful and unburdened, twice. It’s even easier to miss exactly how much impact their histories have on their characters and relationships. It’s brilliant though, and I suppose the point is that Star Wars, like all important works of media, is chock-full of fascinating characters with histories and behaviors that mirror the real world that we live in, and it’s a shame to see anyone reduce them to anything less.
