Hmm, well, if Elves are immortal and Men live, usually, less than a hundred years, then how many cut-short human lives match up to a single murdered Elf? Especially since Men have a nice mysterious-but-generally-good afterlife, whereas the Elves are "bound up in this world". They may get reincarnated but nobody knows what happens to Elves when the world ends. (After Dagor Dagorlad, that is, since they obviously get to fight then, them and all the noble humans, against a returned Morgoth and his hordes of evil.)

You are giving in to easily to the premise... the whole premise is faulty.
