IMC - Nature is not Good or Evil in D&D Alignment terms, but can be both or neither. Druids and Druid organisations can be Neutral Good or Neutral Evil, but tend towards True Neutrality. You basically never get LG or LE Druids; CG & CE are rare but possible. The Lord Weird Slough Feg in the Slaine comic strip would likely be CE, and the Drune Lords as an organisation NE. But I think Feg was corrupted by alliance with the alien Cythrawls, as well as his own desire for immortality, and was no longer truly doing the Will of the Earth Goddess Danu. That didn't stop him drawing on the Earth Power though.
