Ben Solo was not a man who was ‘seduced’ to the dark side, he was a child who was groomed and abused literally his entire life. Ben Solo tried to resist the abuse, he tried to be a good person until the one person in his life (Luke) who had the power to actually protect him from his abuser instead tried to murder him in his sleep. If his own uncle had just given him a chance, had some of that theoretical Jedi compassion for an abused, confused, terrified boy, then Ben wouldn’t have felt like he was hopeless and had no one to turn to except his abuser.
So I will absolutely argue that Ben’s choice to turn to the dark side was not a choice he can be completely held accountable for; with the combined influence of his brain being underdeveloped, being purposefully brainwashed by an adult predator, and having the one person he could turn to other than the abuser try to kill him - this was not a choice knowingly and willingly made. Ben Solo was the victim here.
And Ben Solo is still a victim, doing bad things doesn’t negate one’s victimhood. No one deserves to be abused means no one deserves to be abused, no exceptions. Snoke is the predator here, if you pay any attention to what’s going on in the films you will see that Ben is constantly portrayed as a victim of Snoke and of his own neurodivergent symptoms. Ben is not evil nor sadistic nor even particularly bigoted the way Hux is, he’s (rightfully) angry and has no skills to cope with that; he’s isolated in an abusive situation and an extremist organization that he feels he can’t escape.
Who Ben Solo truly is is a beacon of light that has been manipulated into thinking he is nothing but darkness by a predator who wanted to exploit his power. This excerpt is of Leia sensing Ben in the womb when Snoke first targets him in the womb:
But her baby boy? Him she can effortlessly feel inside her. Not just the way that all mothers can feel the living creature within, but she can feel him with the invisible hands of the Force: with it she senses the margins of his burgeoning mind, she knows his mood, she can tell that he’s healthy. He is less a human-shaped thing and more a pulsing, living band of light. Light that sometimes dims, that sometimes is thrust through with a vein of darkness. She tells herself that it’s normal—Luke said to her, Leia, we all have that. He explained that the brighter the light, the darker the shadow. … My son is alive. The future is bright. (Wendig, 2017, ch. 25)
Right now her son is upset, tumbling inside her as if he can’t get comfortable. His light, flickering with the dark. … The baby turns inside her again, troubled by something she cannot feel and cannot yet understand. (Wendig, 2017, ch. 25)
Leia doesn’t identify the darkness as Snoke until later (again it was Luke’s Jedi-arrogance that kept her from seeing that sooner) but it is confirmed that’s what she was sensing. The visualization of a child that is so pure, that is just this beacon of light being convinced that he is darkness and evil by an abuser who truly is those things is so profound and I can’t even think about it too much without tearing up.
Save Ben Solo because Star Wars is not about condemning abused people for their mistakes, it’s not about us vs. them politics, it’s not about politics at all - it’s a space fairytale about redemption and family, and if you’re too unempathetic and too obsessed with feeling holier-than-thou to appreciate that then maybe you should find a different fandom before TROS comes out because you ain’t gonna be happy.
