SOULs are not canonically quantifiable; that is, where someone can have 1 LV or 15 LV, there is no gray area for the SOUL.

I am leaning towards "Source of Unfallen," as we know the two characters without a SOUL died in the past and have been distorted quite a bit. This also agrees with why the Amalgamates were brought back from being death (according to Mr. Snowdrake), and agrees with the idea that the SOUL does not necessarily relate to other STATS.

This also agrees with the idea that humans store their traits/personalities in their SOULs and not in their bodies - this is why the human SOULs recalled their key items in-life during the Photoshop fight.

You start from the assumption that Chara and Frisk are separate beings from the offset of Undertale - this leads to the idea that Frisk "teaches" Chara when, in reality, they may well be the same person that is "taught" because they subject their free will to the player. We choose which namesake they take on - and they're both very picky about what they need to "wake up."

Post-Genocide Chara may have changed nothing, for all we know. Flowey delivers the same message. We see no monsters dying - just an evil laugh from mainchara and a sepia photo scribbled over retroactively in red marker. We see "Chara"'s smile, but we also know that Frisk smiles, too. It's just perspective. "Chara" may not be ruthless (no STATS were gained this time), but may be reminding us that we beat the game; we defeated the hardest bosses.

The SOUL always resonates with "strange feelings" that Chara cannot understand. There's never a point in which it's devoid of positive emotion; "Chara" may well be the physical body as they control the physical body alone at the end of Geno.
