Feanor Self-Important?

[Aiwendil]

Everything he did was for self-promotion and didn't really care much about anybody else.

I don't want to enter into a blame Feanor/forgive Feanor debate (which I think is a highly subjective thing), but I don't think it's quite correct to say that he didn't care much about anybody but himself. While I agree that he was self-centered, he did at least care very much for his father and for his sons. Cf. his reaction when he learns that Finwe is dead (and I believe there is a comment from the narrator here emphasizing Feanor's love for his father) as well as the story in HoMe XII where he accidentally kills his youngest son - the latter is the only case I can think of where Feanor shows remorse or regret for one of his own actions.
