Well, these are the alternative endings. All of them, in theory, are bad with relation to Ink.

Alternative Ending 1 - A vengeful brother.

After Dream took the powers of Ink, the mentioned begins to chatter but he ignores it and withdraws. Nightmare!Sans grabs Ink with his tentacles, and with a terrifying look he says, "I'll tear out every damn bone and destroy your skull, you will suffer like you made my brother suffer, you filthy rapist." And literally, Nightmare kills Ink by quartering him.

Alternative Ending 2 - Karma charges its debt.

The Bad Guys, Error, Blue and Dream leave Ink behind after Dream took on Ink's powers. When everything was recoded, Ink was still alive but inhabitants of HorrorTale, HorrorSwap, UnderFell, DustSwap! Papyrus and SwapFell persecuted and killed Ink.

Alternative Ending 3 - Severe and dangerous psychosis or dementia.

After the recoding, Ink continued with his hints of wanting to create and create, beginning to rant and becoming very dangerous for the entire multiverse. They all decided to lock Ink in an asylum in MedicalTale, where Ink's madness became so serious that he had a dangerous level of dementia, leading to his own suicide when he believed that one of the hallucinations was real and thought he was attacking someone different, but actually attacked himself.
