What is the theme in The Accident by Elie Wiesel?

One major theme in the novel is the inability to move on.... living in a world when you're really not alive and just going through the motions. The main character survived the Holocaust physically, but he died inside. He died with his family in the camps.... in the gas chambers.... in the fires. Over the course of the story, the protagonist comes to understand that he has not embraced the life he's been given, that his rejection of that life is an insult to those who didn't survive. He learns to forgive himself for surviving, to put away his unearned guilt for what happened to his family.... and he learns to live.
