Were others not equally poisoned, so to speak. Did not Finarfin have the same potential to believe the lies? No temptation to evil is a constant to all, it's how one handles said temptation that determines the strength of character. Feanor failed.

No.

Then Melkor lusted for the Silmarils, and the very memory of their radiance was a gnawing fire in his heart. From that time forth, inflamed by this desire, he sought ever more eagerly how he should destroy Fëanor and end the friendship of the Valar and the Elves

Fiercest burned the new flame of desire for freedom and wider realms in the eager heart of Feanor; and Melkor laughed in his secrecy, for to that mark his lies had been addressed, hating Feanor above all, and lusting ever for the Silmarils.

The hatred of Morgoth was particularly aimed at Feanor.

On the subject of Finarfin - he did fall by turning his back (even unwillingly so) on the Valar and accompanying Feanor and co. He was redeemed before too much damage could be wrought.

Tolkien even calls the slaying wicked.

Unorthodox hero.

I would disagree and call wrestling to protect ones property as simply that, protection of property and not violence.

Throwing people into the sea is a violent act. Life is more important than property - if the Teleri had realised this, perhaps the Kinslaying could have been averted. However, the Kinslaying is perhaps the lowest act Feanor commits (no matter how influenced he was at the time ).

So Feanor threatened Fingolfin with death. Morgoth made him do it. He rebelled against the Valar. Morgoth made him do it. He stole the ships of the Teleri, and then fought and killed them. Morgoth made him do it. He abandoned his brother Fingolfin to almost certain death in the Helcaraxe. Morgoth made him do it.

Exactly. The curse of Morgoth - if such it can be called - lay particularly heavily upon Feanor's head. Feanor was the target of Morgoth's lies and deceit, and Eve of Middle Earth.

The tragedy of Feanor is further reflected in the hints we receive of the power and majesty he could have had, had he not fallen.

Yet had he said yea at the first, before the tidings came from Formenos, it may be that his after deeds would have been other than they were.

The works of wonder for the glory of Arda that he might otherwise have wrought only Manwe might in some measure conceive.
