Hm. Ethics really are time-consuming, aren't they.
I think you might find the rings' efficacy is slightly reduced, here. I haven't noticed that they give me any particular power over my race (which, despite what I might have wished in junior high, appears to be men). Of course, I haven't tried. Which I suppose makes me a moral paragon on the order of Frodo Baggins, so - maybe I can be a hobbit when I grow up, after all.
In any case, I should probably ask around before handing off the theoretical power to control a zombie invasion. I might be willing to part with Narya. Nenya I have a particular emotional attachment to, and one does not simply cast away Elrond's ring.
