Radagast the Brown??

[Elu Ancalime]

but I would say that Saruman and Radagast each failed

Since Sauruman went bad all the way, and Radagast seemed to only have a case of ADD, it think what happened after would be the defining statement: Radagast's spirit was allowed to reenter Valinor, or at least had the potential. Now, then Radagast would either have to go to the Havens (which we should be able to rule out) or have been killed (or possibly died from greif like the elves did???) So ruling out him being slain, something might have happened like this: Many of his animal friends died, and species died out, (eagles became lesser) and so he went sad and 'let go.' I think he would be allowed back to Valinor. Melian was let back in no question, right? So even though Aman was taken from the circles of the world, i think him being an Ainu he could let his spirit go back.
