What is a thesis statement for Boxer and Napoleon?

Consulting the original assignment and assessing if there
are any stipulations or requirements would be considerably helpful in your task.  You
might have to include some elements that would help you construct your thesis
statement.  Outside of that, I would say that your thesis statement might want to
revolve around the idea of power.  Napoleon holds power over Boxer.  He is able to exert
this power in obtaining whatever he can from Boxer, who is a complete apologist and
supporter of the power structure.  When Napoleon no longer needs Boxer, he arranges for
him to be killed off.  Essentially, when the power structure has extracted what it
needs, it discards those who support it and prop it up.  I think that a thesis statement
around power and hierarchical structures tend to favor those at the top of it at the
costs of those underneath could be a starting point.  Another avenue that your thesis
statement could go would be to the idea of how Boxer refuses to question authority,
inevitably causing his destruction.  The idea of "I shall work harder," ends up being
Boxer's own death warrant.  I think that a thesis statement about how loyalty in a
political system tends to disempower those at the bottom of the order and empowers those
at the top of the structure might be another venue to which the thesis can be
directed.
