I think the concept can work for Error if you dive deep into how he would actually respond to the situation. I don’t believe he’d go limp and let it happen— I believe he’d convince himself he LOVES destroying in order to cope with it, and likely would start comparing himself entirely to his actions. He’s not a good person, and he knows it, but he’s still confident in himself and doesn’t feel sorry for what he’s done as he believes it’s all he’s good for. Not even in a self-deprecating manner but in a way where he truly believes that’s his purpose and what he was made for— what keeps his magic alive and what entertains him. Sure, maybe he didn’t start out wanting to do this, and he truly would prefer a quieter life outside of destroying, but he makes himself content with what he’s given and he won’t complain. He learns to love it, even if it twists his mind and makes him not trust in longevity.

Also making Ink the bad guy in these plots is a bit overwritten. I think the most accurate way to portray Ink in a FGOD Error situation is him unaware of Error being forced and thusly believing he’s doing what’s best or him also being forced, and still unaware that he isn’t alone in the control. If Error is super confident in what he’s doing and still cruel, I do think Ink would overlook the signs that Error isn’t the one calling the shots.

I don’t know. I think FGOD is a really cool concept, just usually rewrites the two to be a bit off. I believe there’s ways to write Error to be sympathetic in the situation while also sticking to him being an asshole and getting a thrill out of what he’s doing. Perhaps he never wanted it, but it’s all he’s got now, and he’s gonna make it wonderful because he believes everything he does is wonderful. It would make pulling him out of the situation more fun for sure, as he’s so stuck in his ways but parts of him does yearn for peace. Paints for a good misunderstanding between Ink and Error that would be fascinating to explore how it effects them— with Error not knowing that Ink is blissfully unaware of why he does what he does and Ink believing there’s no point in saving him when he’s so far gone. And yet, as the story unravels, they realize that the other is clueless to what they’ve been put into and how that realization affects everything between them.

The castle's hallways are always suspiciously well lit and sparce during Error's visits. No nightstands with elaborate arrangements flowers resting on top under the windows, no suits of armor standing tall and proud, just the occasional sconce, burning bright enough that you can see the corners of the hall.

Error figured the castle always looked like that. It was only after Dust offhandedly mentioned Killer hiding in one of the suits of armor and Cross nearly skewering him when he jumped out at him that he was informed the castle halls are typically decorated.

He brings it up with Nightmare and he simply says, "I told the castle to be hospitable to you, it knows I owe you a great deal."

Error just huffs and goes, "you don't owe me shit... and t-the hell do you mean you told it to?"

"This place has a mind of its own. I figured you'd noticed by now. Isn't the code any different?"

"The fuck do you mean? Your freakish universe is hardly even made of code, that's the only reason I haven't torn it to shreds yet!"

"Hm. Discuss it with the others. I'm sure they can give you more insight than I can."

Error grumbles at him, "I'm not discussing anything with your pet projects, tentacles."

"If you say so. Did you need anything else?"

He completely can't remember now. "No! ... Maybe? Fuck off, I'll be back later."

"Come by whenever, then."

but fgod sounds like a lie canon error would pull to play the victim. like he so would make that shit up to gain sympathy/attention. even when it has glaring flaws that gradually become more obvious. and then maybe trick himself into believing it when everyone else slowly realises it's a lie.

Personally disagree because Error does not feel the need at all to lie about what he plans on doing because he sees it as righteous
