What is the plot of "The Guest"?What events took place

Set in remote Algieria during civil unrest between French
colonists and Arab natives, "The Guest" features Daru, a French (in exile) schoolteacher
who is host to Balducci, a French gendarme (military guard), and an
Arab prisoner accused of murder.  Daru feeds and harbors the two guests for the night.
 The next morning, there is an uprising by the native Algierians against the French
troops nearby, so Balducci leaves the Arab in Daru's custody while he goes to fight,
thereby leaving Daru the responsiblity to deliver the Arab to the nearby
priosn.

Because Daru in an Arab schoolteacher, he
sympathizes with the Arabs and does not want to get involved, especially in a death
penalty case.  But, he is also a French colonist (by proxy) and faces chargesof treason
if he does not obey Balducci's orders.  So, he tries to play both sides.  He walks the
prisoner to a fork in the road: one road leading to prison, and the other toward a group
of nomads.  Thinking the Arab will choose freedom, Daru frees him.  Looking back,
however, Daru sees the Arab walking toward the prison.

Why
did the prisoner choose death instead of freedom?  Why did Daru refuse to choose another
man's fate?  Was Daru's decision to "wash his hands" of the prisoner an act of
irresponsibility?  Was it a cultural decision for the Arab to honor the wishes of his
host (Daur) and thereby go to prison?  Or, was it a fear of freedom?  Does Camus think
that most people choose death instead of freedom every day of their
lives?

In the end, Daru finds a message at his schoolhouse
left by the Arab's brother which says he plans to seek revenge for his brother's death.
 So, Daru's refusal to make a choice inevitably leads to the Arab's death and possibly
his own.  This predicament reflects Camus' absurdist philosophy which says the universe
is chaotic and unsympathetic.
