Short of throwing Earth itself into a volcano (no, that wouldn't work, make it the sun instead) I don't think it's humanly possible to eliminate evil. Humans inherently have evil in them. But also good. Unfortunately it often seems the default setting is 'evil'. There definitely is good and evil, but you can only really classify actions that way. However I'd say Hitler for example qualifies as evil. (or Sauron, Morgoth, etc) The one thing that bothers me a little in LotR is that the orcs are depicted as totally evil. I don't see how this is possible in any creature capable of rational thought and choice.
Great topic btw.
