Which Elf had it hardest?

[Knight of Gondor]

I didn't think too much about Elrond, but when you put it that way, I suppose he would be an excellent candidate for "worst life". Then again, I forget whether or not the book backs up Cate Blanchett's quote in the movie: "To be a Ringbearer is to be alone". It makes sense, though, for Elrond.

The Elf that came to my mind was...and help me if I'm getting his name mixed up with someone else's...Beleg? The friend of Turin Turumbar, who Turin slew by accident, taking him for a foe in the dark light. Of course, Turin would be the most suffered man to mention...
