Edgar Allan Poe-"The Fall of the House of Usher"

          "The Fall of the House of Usher" is a thrilling short story about a man who goes to visit a childhood friend of his because his friend had written to him and told him that he was sick. The narrator goes to his old friend's- Roderick Usher- house and sees for himself that his friend is in fact sick. Roderick explains to him that he and his sister are the last of the Ushers, and she is about to die soon. She then does 'die', and they put her in the basement area in the house. One creepy night neither of them could sleep, and Roderick thinks he hears his sister and is scared that they buried her alive. They check downstairs; she was covered in blood standing in the doorway and throws herself at Roderick, and he eventually dies. The narrator runs away from the house.
           I enjoy Edgar Allan Poe short stories, especially The Fall of the House of Usher. This short story was weird and very entertaining. It kept you reading because you always wanted to know what was going to happen next. The spin at the end was great. In general I like Poes odd writing style.     

Question: Did she intentionally kill him?
