Feanor and the Silmarils

Do you think Feanor made the right choice in leaving Valinor for Middle Earth? I think he had the right to leave, but certainly didn't have the right to do the Kinslaying. Of course, had he not come to Middle Earth, the whole LotR story wouldn't have happened. (Forgive me if I've gotten my facts wrong, I'm pulling them from memory, as my copy of the Sil has vanished )
