Yeah, I'm writing up two separate blog posts about these things - they're nearly done. :'D

The incredibly brief version is this:
 * "Chara" does not provide determination - they are awoken by either ours or Frisk's.
 * We are not Frisk, as Flowey tells us (he perceives us as "Chara") to leave Frisk alone, and let them live their life.
 * We must be something else.

This is why I don't think that the red SOUL is "Determination"... that stuff gets extracted from all human SOULs. More accurately, the red SOUL may represent Fate. The protagonist follows the lead of a supernatural force (us) to whatever conclusion we see fit.

Fate: (n) "the development of events beyond a person's control, regarded as determined by a supernatural power."

Heyo. ^^' This is a mix of two theories. Apologies. I hope it gives you something to think about, though? c:
