Execution of personas, and the meaning behind it? (Lore)

I was wondering why when you execute a persona. (Or collecting a new one) for example when you execute Arsene for the sake of a new one, is it still the embodiemnt of the rebel soul at all? Is it the same just stronger? After all, the shadows, from my understanding at least, were born of the collective unconscious, which their embodiments can vary. and because it's a new mask we put, a new persona...is it the same?Hence one would think it's a new embodiment of will. An embodiment of a diffrent emotion within us?

A side question If a persona is an archetype, Then does that mean the tarot cards are as well? I'm asking since Igor said that the personas are realted to the tarot cards, hence we need to tighten our relationship with friends and the like, only then we would be able to strengthen a persona corresponding with that tarot/friend.

I'm not so sure though...
