Dr. Graham explains that he has been driven by curiosity and a desire to solve the scientific puzzle presented by the weapon. He acknowledges that the weapon can be misused by those in power, but he believes that knowledge cannot be undone, and once it exists, it will be discovered or replicated by someone else eventually.

Regarding the last line of the story, "Only a madman would give a loaded retriever to an idiot!" - it is a metaphorical statement made by Dr. Graham.
