There is a quote from Chara (the demon that comes when you call its name) that solves this dispute, somewhat.

Chara is basically a demon anyway, especially if they were reincarnated as one. They even have that jumpscare.

Because of this, I believe sans saw Papyrus welcoming him into heaven, so yeah, Heaven and Hell probably exist in Undertale, but I'll stay out of that.

In conclusion ... yeah.
