In Night, how does Elie change throughout the memoir?

Before
Elie enters the Auschwitz concentration
camp and experiences the horrors of the Holocaust, he is
a devout Jew and
dedicates his life to studying the Talmud and the Zohar. Elie spends the

majority of his days praying in the local synagogue and learning the secrets of the
Kabbalah
from Moishe the Beadle. Elie also does not have a particularly close
relationship with his
father, who is a revered community leader and attends
to his business rather than spending time
with his family. After Elie and his
family are transported to Birkenau, he is immediately
separated from his
mother and sisters and remains by his father's side. Once Elie and his father

pass the first selection, they become inseparable and rely on each other to survive
the
harrowing experience.

Throughout his Holocaust
experience, Elie witnesses
indescribable horrors and lives in perpetual fear
of being beaten or murdered by SS officers.
His perspective on life
dramatically transforms and he ends up losing his faith....
