Caine is 100% evil based on the info we have about him and his behaviour. But Goose and his VA and the show want to believe Caine is just a misunderstood baby. This dude:
Had their brain scans all along.
Made them bodies that mock their issues irl.
Lied about a lot of things.
Is probably the reason abstractions happen (Scratch the fist abstraction line from Kinger). Meaning he tried to mindbreak Scratch to fit his wishes.
After 20+ years with humans somehow “doesn't understand them”. He doesn't understand them but knows how to hurt them and mock their issues very well.
Named himself after the first human mortal sinner from the Bible. The fact that he named the puppet in ep 7 Abel means Caine is indeed aware of Cain and Abel. Which also means Caine is aware that he “killed” his brother, the other AI. I know Caine stands for something else, but this show is badly written and that info is on Goose's social media so it doesn't count. His name being a reference to the Bible is a meta thing that doesn't make any sense in canon and if you take this seriously then indeed Caine is aware of his actions, has killed his brother, and is a bad person but doesn't care and plays dumb. Acts like a silly willy, refusing to change anything for 20 years.
Says he wants humans to like him, yet spends all his time with Bubble instead of actually communicating with humans. Meaning he wants others to do the job while he just gets praise.
Despite there being several adventures that the characters like, Caine doesn't seem to care even though his main motive is supposedly to be valued for his adventures. Ragatha says adventures are good for humans and keep them stimulated, Jax enjoys the adventures because he can do whatever he wants during them. But for some reason Caine, “I just want people to like my adventures,” doesn't give a damn about this. Once again it's because this show and Caine's character are written badly.
In ep 8 he tortures everyone after getting a cringe personality switch. Plus in this episode Caine sings his song in which he's pretty clear about his bad actions while simultaneously torturing the characters more.
"Seems our regime has plummeting south"
"So just play the games and ignore the pains"
"Not enthused just feeling used? What a goddamn shame"
Blames innocent people for his misery.
I should also include him keeping the blue AI hostage for 20+ years just so he can achieve his goals.
Butttttt at the end he just removes the blue AI (it's not a person for some reason even though blue and red are equal in their development as we see in the first scene in episode 8), sends it to fly in the void, and comes back with a therapyspeak monologue and everyone accepts him.
Another thing that's interesting is how blue AI is his victim and it's shown as an object. This is not the first time in this show that the abuser gets sympathy and the creator wastes all time on their "development" while their victims are getting jackshit. Of course nobody hates Caine! Blue AI is just an orb it can't say anything! Good thing it's just a thing isn't it?
Yes Caine, it's good to have you back, says Zooble. Yes, this dude is redeemable! Oh the abstractions? The fact that nothing about them is resolved? They are still stuck as shallow husks of themselves after a severe mental breakdown? Everything Caine did throughout his existence? Um, who cares, he's chill now🫶 What a redemption arc. He just didn't know how to understand humans, guys😢 Good thing he randomly got WiFi and looked at their social media so he gets it now for some reason.
All of these are the consequences of Caine getting that personality switch in ep 8 just so he can have his Temu AM moment. He was such a cool reverse AM AI character who was driven by his love for humans, but then in ep 8 he just becomes evil and it's revealed he had their brain scans. He's a malicious person. But then they still redeem him. It's not even a redemption; he can't fix everything he's done, he just goes "my bad blue AI I let you go after controlling you for 20+ years! sorry guys I won't be like this again". We are supposed to think he's one of the friends now. He's having fun with them at the end too. Bruh
