Obviously, the Nine Rings turned nine men into Nazgul, so they are bad. But less is known of the Seven Dwarven Rings. Do they corrupt? They don't appear to have ensnared the dwarven lords to Sauron's service. Also, the Three Rings of the Elves don't appear to be evil, yet Gandalf calls the Great Rings "perilous" and says that they would make mortals fade if used too much and would have bad effects on them. Does that also apply to the three Elven Rings? The only one that we know that had them that wasn't an Elf was Gandalf, who was a Maia, which is, from what I can gather, a "super Elf" with the ability to shape shift and with more power than most Elves (at least concerning power, immortality, etc.) If Bilbo, Gimli, or Aragorn were to long possess one of the Three Rings, would it hurt them? What if they had one of the Dwarven Rings? Would those hurt Bilbo and Aragorn (The Dwarves don't appear to be ensnared to Sauron by them, so likely Gimli may have been immune, though maybe Legolas wouldn't have, especially as the Dwarven Rings were made by the Enemy, and maybe Dwarves were just too hardy but the other kinds would have fallen.) Also, while the Nine Rings were likely the most perilous to mortals, would they have any significant effect on Legolas, Galadriel, or Gandalf if they kept them?
