Korvin your post made little sense.
If what you are asking can one be truly neutral while remaining a citizen, the answer is yes, we do. We not forsake someone because they are from another city, nor will we help someone more if they are from our own.
In other words, we do not even think about what city, nor your alignment, nor your profession when we heal. However, as Conteck stated, if we cannot diagnose you, we are not obligated to heal you.
