Seriously, though.
A charater does not have to be "flawed" in order for a change or arc to occur.
A charater can simply have a standardly held belief, neither good or bad or popular or unpopular, that situations and experiences across the story change to either an opposing belief or simply a different belief.
The theme of the story may be heavily, lightly, or not at all related to the protagonist's change.
As far as it being "opposite", the two are as different as location and character; maybe yes, maybe no.
