Fingolfin's Death - Suicide?

[Inziladun]

I put Fingolfin's attack on Morgoth in the same vein as that of the Rohirrim at the Battle of the Pelennor in ROTK.

There Éomer, seeing the apparent death of his uncle and sister,

....stood a moment as a man who is pierced in the midst of a cry by an arrow through the heart; and then his face went deathly white, and a cold fury rose in him, so that all speech failed him for a while. A fey mood took him.

There's the word fey, to accentuate the likeness. After that, he rides toward the enemy yelling "Death".

In both instances there is a moment of despair, followed by a white-hot rage to avenge, and though I don't think dying in the act was the preferred outcome, neither Fingolfin nor Éomer were concerned at all for their safety.
