It seems to be a case of unknowing possession to me, Frisk is possessed and being controlled, but they don't know or realize it. Thinking that everything they do is there own decision and choice, and not some unseen entity's decisions and choices. It's just not Chara as the entity in question, they are there, just not the entity pulling the strings.

Frisk still is determined, and willing to never give up, on there own. So with or without the Entity, they'd still do what they do in the game.
