Elie Wiesel's account of the Holocaust was written years after the event took place. How might Night be different if it had been written as a diary, a first person account of events immediately after they happened?

it would be slightly different than if he had written it directly after it happened.

Explanation:

Peoples memories change everytime they remember them, based off of their emotions at the moment and new life experiences. This would change somebodies knowledge of what happened. First hand accounts are always better, because it is fresh in somebody's mind.
