What are the narrator's descriptions of himself as the story "The Tell-Tale Heart" develops? What are some words and phrases to describe his personality?

The narrator is our source of emotion in this story. He grows more and more scared and horrified as he functions like a camera lens to focus us the reader on what is happening.
