No where that I am aware of are the noldor cursed by the Valar. The Doom was I think merely a foresight that they would become enmeshed in an altoghether ineffective [ I won't say fruitless] Attempt to regain the Silmarillis and or avenge Finwe.

Why were they karmically ensnared?
1] The kinslaying
2] No Blessing of the Valar to go - It was the wrong time, to spread their wings and live on their own and to fight Morgoth.
3]Morgoth would turn his evil will against them and it would be [ as the valar knew] more than the Noldor [mighty , brave and strong s they were] could stand up to.
4]They were reacting to Morgoth's events [which the valar refused to do] instead of patiently searching out the Will of Eru [ in their hearts or via manwe and co.]

So for all of those reasons [ and not all apply to each Noldor, but most apply to all and their descendants and 1/2 descendants like Voronwe] they were ensnared in a web as it were. As were Thingol[ and thus his entire kingdom], the moment he sent Beren after the Silmarill [Melian says as much] and Beleg [ through his involvment w/ Turin and thus Morgoth's curse on his family].

So the Silmarillion you could say is largely about the interconnectedness of friendships and life, and how even those fighting a bad guy or in this case THE Bad Guy, can do so from less than pure motives or a less than pure position.

From the get go JRRT is trying to teach, I think humility. Through Feanor's utter lack of it and his angry and swift end, to Galadriel, having some meausure of it in going to learn from melian and leaving Beleriand before the mess came down around her head [a result and measure of her relative innocence perhaps].

Indeed this lack of humility on the part of Feanor's sole grand-child plunges the world into another age and a half of war!

He was warned by Gil-galad and Elrond not to treat with Annatar[?] but he clearly did as he thought best.

As the chinese say an error of an inch in the begining leads to an error of thousand miles in the end.

Of course repentance is always [theoretically at least] possible and we see characters such as Boromir take this for themselves.

Galadriel herself must pass through the final temptation of the ring as must Gandalf, Elrond, Aragorn and Boromir and Faramir, nearly all of the leaders of the west [Denenthor was relieved of this burden by his son, and this was a great part of his wrath towards Faramir].

So the Doom of the Noldor reverberates down through 7,ooo or so years and is only fully resolved by Frodo, Sam and Gollum , with the aid of the wise and the Numenorean exiles.
