In the Eyre Affair, literature is a very highly valued piece of work. Whether it’s time travel, vampires, or crazy inventions, the world within the novel is definitely extraordinary. The characters within the book do note on the bizarre nature and mysteries of their world; however, these crazy things are still within their social norms.
When the evil Acheron Hades is first introduced, the fact that he has supernatural abilities (such as his hearing and cannot be killed) is definitely marked as amazing and far-fetched. But when it is discovered that these abilities are all real, it is relatively easily accepted by those after him. This is because crazy things are normal in this world!
With that said, I think it would be very easy for a person in the world of The Eyre Affair to view these crazy abilities as talents – whether they are labeled “good” or “bad” talents are irrelevant. They are still talents.
Imagine a world in which you have the ability to crush metal objects with your mind! You go from crushing cans to crushing incoming bullets to eventually crushing cars and planes. Regardless of if this talent is being used for good or evil, that is still extremely impressive! I believe that is the mindset that the characters of The Eyre Affair have in regards to these talents that create such monstrous acts.
Once one is able to overcome the shock and disbelief of a talent, then it is able to be appreciated. When Thursday notes that Hades is very impressive, I think the fact that he is doing bad things stumps people. I do not believe that Thursday is condoning these actions by paying Hades a compliment. I believe that since the evil within Hades is normal to her, she overlooks that fact and strictly bases her comment on the talents in which he posses.
