As much as you try to deny the obvious, Maedhros, it appears to me that it was a threat. A warning, telling the Noldor not to travel to ME, or else. It partly worked, in that it changed Finarfin and his people's minds. They didn't go to ME. They heeded the warning. They thought "Hey, wouldn't it be a good idea to stay here, and not have to go through all that trouble?". The Doom worked on them. But it's purpose (to keep the Noldor in Valinor) did not come to pass, as the Sons of Fëanor and their followers ignored the warning, and went on their merry way to ME. The Valar did not decide "Hmm, those Noldor are becoming annoying- let's give them pain and suffering until the end of time". No, the Valar loved the Noldor. They knew what was best for them: to stay in Valinor. So they made up the Doom of Mandos to warn the Noldor to stay in Valinor. But it did not work. It was a failure. You appear to be clutching at straws, dear Maedhros, and rather short ones at that. The Doom does not say "and the Valar will fence Valinor against you, and shut you out, so that not even the echo of your lamentation shall pass over the mountains unless you have a Silmaril; in which case we will gladly accept you back, and take back this Doom." It says that they will not allow them back into Valinor, period. But what happened? One of the little buggers snuck through the 'fence' and reached Valinor. And let us not forget the eagle that Manwë sent to Fingon in pity for Maedhros' (once again, the elf, not the debater ) precarious position. Fingon prayed to the Valar for pity, and Manwë sent an eagle to help carry Fingon to the bound Maedhros, and to fly them away from Thangorodruin. Fingon's lamentation certainly reached the Valar there... Therefore, that part of the Doom did not come to pass. So Manwë over-ruled the Doom before it could come to pass entirely? Doesn't sound as if it were completed...and therefore it mustn't have achieved it's secondary purpose of punishing the Sons of Fëanor and their followers for not heeding this threat beforehand. So we have determined that this warning/punishment did not achieve it's purpose in that: A/. It did not prevent the Sons of Fëanor from leaving to pursue Morgoth. B/. It's predicted punishment did not come 100% true. C/. It was called off by Manwë before it's resulting punishment had entirely come to pass. Edit: Fixed a couple of vB code errors. Sorry.
