Alright so in Kingdom Hearts there is this cute neat little thing called DARKNESS that is a huge force and shit, DARKNESS is a thing you can physically interact with (you shouldnt) and a power you can use (you probably shouldnt). In Kingdom Hearts, when your heart falls to the DARKNESS (or your whole damn body) 2 things happen, your soul (heart) becomes a creature of darkness (or can just exists as its own being with conciousness depending on how edgy you are) and your hollow body keeps going as a wretched beast (and if youre particularly strong, it retains your personality and physical likeness).
My absolute crackhead triple stunt theory is that that exact thing happened to December, she found DARKNESS (posibly with Kris and Asriel somehow involved), she fought it/tried to fight it and lost, her body became the Knight (which would explain why it looks like a corpse and why it behaves so erratically while still having a sense of "self") and her soul/heart ended up trapped in the code refusing to die.
Thank you for coming to my TED talk I will now go back to obsess about seemingly unrelated bullshit for hours on end.
