Because unlike Griffith who actually pulls moves and makes shit happen behind the scene Cinnabar is the passive observer that shit just kinda happens to, devoid of any agency up until the point where she realizes that Phos is the protagonist of the story.
And the first thing Cinnabar does after realizing this?
Backstab and actively fight against Phos because her life finally has meaning after Phos became the persecuted party.
Instead of joining together with Phos in a cause that Cinnabar knows deep down that she would have enjoyed riding out just as much as staying on earth.

They are the exact same person but Cinnabar is just Phos if Phos was bitchmade.
That's why Cinnabar doesn't even blame Phos for what she does, which just makes Cinnabar more unlikeable imo.
