Rose and Scar are very dear to my heart because they were the first non white anime characters I saw in my life. I was the "he just like me fr" meme for them when I was little, so I am very happy that you find this man fascinating
He's a mess and the fact that a brown anime guy from the early 2000s is allowed to be messy and complicated and morally gray without being demonized AND staying as a fairly handsome bishounen (as opposed to the scary brown man stereotype) feels like a miracle in retrospective
I HAVE ONLY SEEN TO EPISODE 23 OF THE ORIGINAL ANIME PLEASE DON'T SPOIL ME AND ALSO BEAR THAT IN MIND.
Flashbacks to childhood me clinging to Fievel Mouskewitz and producing the largest stretches you've ever seen to explain why a character was Jewish, actually. (At my big age it just becomes, 'because I said so' but solidarity) It's so funny how seeing a sliver of yourself will make you insane about a character.
I think when this show is at its most ON is when it asks us to hold multiple things about characters, and Scar is a fantastic fucking example of this. He's a tragedy, he's a nightmare, he is a victim and the cause of half his own problems. He's not wrong, he's driving himself away from his people--who he loves! But he can't separate himself from revenge long enough to love them. He's letting himself be powered by hate, it's so understandable, and so tragic, and if he could let himself love his people more than he hated State Alchemists, what could he accomplish?
(This isn't even getting into what is going on with him religiously. Talk about stuff I privately rotate in my head at all angles. Fall of a sparrow ass shit as he's plotting some abstract suicide. Amazing.)
I LOVE all this about him. I will be SOOOOOOO disappointed if the show ends up coming down on either, 'Scar is a villain' (untrue) or "Scar did nothing wrong' (also untrue) because I think going to what you're saying, in addition to not being demonized he is ALSO not pedestaled in that awkward way that can happen in shows (and fandoms) sometimes where the brown character can't ever do something shitty, isn't allowed to be wrong*. It's dehumanizing from another angle. They don't do that! Scar is a fucking PERSON trapped in this fucking nightmare society and he's doing the same thing as Ed and Roy: Continuing to follow the path a younger self put him on and refusing to see any and all offramps. SUNK COST BAYBEEEEEE. (They should just rename the anime this)
There's things I want for a character NARRATIVELY and things I want for a character PERSONALLY, and on a character level I want Scar to do the same thing I want Roy and Ed to do personally: Stop! Just stop. You can't fix it, you can't avenge it, you can't do jack shit, but you can walk away. You can do something else. You can live a life and do better but also I fucking love that Scar is produced with incontrovertible evidence that his people are still there and I would argue still need him and is still like, "ANYWAY. Uh, continuing my insane journey for reasons" He will not let go of his own personal watch! It's a slow-motion tragedy!
(Narratively I sort of think all three of them could die and it would fit their current trajectory, and depending on how dark you wanted to get with it I could see a lot of paths to that. Narratively I will accept a lot of answers assuming the writing supports it, but if I had to end this show tomorrow there might be a pile of bodies. On the other hand, I am sometimes a sucker for a hard-won healing. Not an easy one! But I could really enjoy a well-written version of Scar where he DOES decide to bury his brother, finally. And be something for Ishbal. It's hard, and it sucks. It's a fucking miserable grind back toward being obsessed with life instead of death, building instead of destroying, but I think it could be REALLY satisfying for his character. Now, am I sure this show has the chops and willingness to do that? Eh, not really, so I'll just have to see what it gives me)
ANYWAY WOW YOU DIDN'T ASK FOR ANY OF THIS. SORRY. In conclusion, I'm not even sure I "Like" Scar in like a....dollie way but Jesus christ every time he is on my screen I am so interested in what is going on in his head. I love him in the same way I love like, The Green Knight movie. I am fascinated I am compelled I bet his character is INSANE on a rewatch. I still remember my reaction to the first time he showed up i was basically Jay from Dogma: Who the fuck are you?! Why did you just explode that guy's head?? What a ride.
*If you're a fan of brown men's wrongs I really recommend Interview With the Vampire. 2/3 leads are brown guys and they (all three leads) suck absolutely while being utterly captivating. My favorite is actually probably the biggest fucking dick in the whole show, he was tailor-made for me, love him. Fucking asshole.
