In "Civil Disobedience," how are Thoreau's perceptions of his fellow citizens changed by his night in jail?

Civil Disobedience is an essay about Thoreau’s ideas about
the government and his recounting of the time he spent in jail for not paying his taxes.
After his release from jail, a friend paid his taxes for him, Thoreau reflects on how
his perceptions of his neighbors has changed. Thoreau claims that he has a better
understanding of the way the world works when he says, “I saw yet more distinctly the
State in which I lived.” His awakened vision is what allows him to look at his neighbors
and he makes this comment, “I saw to what extent the people among whom I lived could be
trusted as good neighbors and friends; that their friendship was for summer weather
only.;…” Thoreau makes reference to the idea of his neighbors being only fair weather
friends, people who are friendly or at least are civil with only when it costs them
nothing. The first change in his vision of his neighbors is that he has lost so much
trust in them that he does not even consider them to be his neighbors any more. Thoreau
furthers the idea that they are foreign to him when he says, “that they did not greatly
purpose to do right; that they were a distinct race from me by their prejudices and
superstitions, as the Chinamen and Malays are;…” Thoreau once believed that he and his
neighbors had common beliefs but now after his time in jail he does not see any
similarities between himself and his neighbors. Thoreau continues to expound on these
differences going so far to suggest that they have given up what it means to be human
for comfort and security when he says, “that, in their sacrifices to humanity, they ran
no risks, not even to their property; that, after all, they were not so noble but they
treated the thief as he had treated them, and hoped, by a certain outward observance and
a few prayers, and by walking in a particular straight though useless path from time to
time, to save their souls.” Thoreau transitions from saying that those who were once his
neighbors now no longer share in any similarities to himself, they have false beliefs,
they have given up what he considers humanity for comfort and even goes so far as to
suggest that they through their complacency have elevated the thieves (government) to
some form of deity that by obeying will have no discomfort. Thoreau does give his
neighbors some forgiveness when he says, “This may be to judge my neighbors harshly; for
I believe that most of them are not aware that they have such an institution as the jail
in their village.” The forgiveness come through in the patronizing idea that I saw yet
more distinctly the State in which I lived. I saw to what extent the people among whom I
lived could be trusted as good neighbors and friends; that their friendship was for
summer weather only; that they did not greatly purpose to do right; that they were a
distinct race from me by their prejudices and superstitions, as the Chinamen and Malays
are; that, in their sacrifices to humanity, they ran no risks, not even to their
property; that, after all, they were not so noble but they treated the thief as he had
treated them, and hoped, by a certain outward observance and a few prayers, and by
walking in a particular straight though useless path from time to time, to save their
souls. This may be to judge my neighbors harshly; for I believe that most of them are
not aware that they have such an institution as the jail in their village." The
forgiveness come through in the patronizing idea that they are this way because they are
unaware. His neighbors lack the knowledge of jail and that the threats that it holds are
far less damaging to a person than giving in to the tyranny of a heedless government.
Thoreau himself gained a firsthand education about jails from as he refers to it an
institution, and obvious play on the idea of schools and colleges also being called
institutions.
