Not really. I had an English teacher that made us read the thing freshman year? Surface reading is taking it at face value. Go deeper? And Porhyria saw the narrator as a friend taken ill...she didn't know he was obsessed with her. She was probably dressed up to go to a party, or to see her real lover, and checking in on him was a pit stop. When she went to kiss his cheek like he was her brother or something, he got all crazy and killed her rather than accept that she would never truly love him.

The guy was sick or...mentally ill or something.
