Maybe some things are just meant to be left hanging.

Examples: Asriel being left in the underground alone and never seen again. Chara and Frisk's life above the surface. Chara's reason for climbing Mt. Ebott (we know it was probably suicide, but why?). The other fallen humans' stories. Gaster's followers. What Gaster looks like.

There are a bunch of other mysteries, but I think you get the point. I think Toby wanted us to interpret it, and people did. I don't think we will ever know Gaster's story, and I don't think we need to.
