Nebulous "It" and Absolutes

[Imladris]

But Frodo is hardly allowed to make a free choice & is told by both Gandalf & Elrond that he is meant to have the Ring, & that the task is appointed for him & if he doesn't find a way, no-one will (shall we translate: 'if you don't succeed in detroying this Ring we'll all be killed or enslaved, & it will be all your fault'.?)

I wouldn't say that. What I think Galadriel is that the only person who had a chance of doing it was Frodo. Everybody else was either too foolish (eg, Merry and Pippin) or had too much power that could easily be enslaved to the ring (eg, Gandalf). I believe I read in another thread once was that they knew he would fail...how could he not? They knew he was "human" and had his faults. They knew there was not much hope. Why would they blame him for that?

Of course he suffered wrong. But this is an imperfect world. No one would have suffered at all if Melkor hadn't gotten on his high horse and corrupted Middle-earth. As hard as it is to accept, this is the way that Middle-earth and our world works. It's unfortunate, but it's the hard truth. There is suffering in this world, and none of it is fair. But what can be more beautiful than a few soldiers giving up their life, their happiness, for the good of the human race? It's called self-sacrifice. Would you rather have Middle-Earth suffer under Sauron because what would happen to Frodo would be wrong? Would you rather have Sauron king of Middle-earth because what would happen to Frodo would be unfair?
