Dude, that major had been presented as crook and opportunist from the start, the passage obviously describes him being corrupted by greed. Especially since we know that in Tolkien verse corruption is a thing that can actually happen and will have phisical simptoms, like with Mouth of Sauron, or Gollum. So yeah, it could be called a disease, but not because you can just catch it like the flu, but because by giving in to greed one can become corrupted and it will end badly for them.
