Is there anything ironic about the narrator's role in "The Fall of the House of Usher"?

Yes.

The narrator's role is primarily ironic in his relation to the psychic tumult observed. That is to say, when the story opens, the narrator speaks of the gloom and oppression the House of Usher brings into his spirit. It is about him, and seems to be concerning, even obsessing him. The same is true when the story ends; this is a very self-centered narrator. He's concerned about the effects on his own mind and spirit—but the truth is, this is another house/family/person going made. He's so concerned with keeping his own "house" in order that the deterioration of another's is of relatively little importance.
