Who said Frisk absorbed Chara's conscious? Who said they ever absorbed your soul?

You do sell your soul to Chara but is that an actual absorption? What did Chara absorb your soul into? They're just a spirit right? They have no body so they have nowhere for the soul to go.

Then again, I also just went through a long explanation about how I don't think Frisk is human, so I don't know how this is supposed to compel me.

Chara never outright says they have no soul, just that their human soul and determination was yours. You interpret this to mean Chara has no soul, but I think that would be a vague and unintelligent way to get that point across. Why include the part about determination if this is supposed to express they're soulless?

A more likely interpretation is they're just talking about how your soul and determination is now theirs (least for the time being). Notice they use past tense "they were not", in the past they weren't theirs but now they are.

Course, that could be completely wrong but that I think that a more simple and likely explanation then what you proposed.
