Wiesel concludes his work by writing “a corpse gazed back at me, the look in his eye, as they stared at mine, has never left me.” Discuss this statement

Elie is talking about the reflection he saw in the mirror.... he hasn't seen his reflection in years, and the man who looked back at him looked like a corpse.... a dead man. He was weak, undernourished, and old beyond his years..... just a shell of a man, as close to death as he was to living.
