Actually, the ones most concerned about Sofia are not the residents or the police of Amstan, nor are they the Huaxia citizens, but the church.
However, the church cannot decide how best to approach Sofia, and from her past attitude, she doesn't seem to have much recognition of the church—at least she decisively killed Saint Judge David.
But to declare her an "apostate"? That's also impossible, as no one can prove she's committed any blasphemous acts.
It's quite amusing to speak of, David secretly absorbed the power of Jinwu Sunflower, but in the church's propaganda, he's a hero.
And Sofia being declared an apostate was simply because she temporarily possessed the Jinwu Sunflower.
Subsequent facts have shown, she also absorbed the power of Jinwu Sunflower—otherwise, she wouldn't possess such bizarre supernatural abilities.
But when she was sentenced, she truly didn't show any signs of abnormality, didn't resist, just quietly escaped.
