Who do you reckon is the braver race in general, men or elves?

Maeglin was a single individual (and by no means representative of Elves in general); however, I was referring to betrayal in battle by large numbers of men, such as Uldor and his entire host of Easterlings in the Battle of Unnumbered Tears. If you are referring to betrayal outside of battle (as Maeglin would be), then there are the cursed army of men of the Dimholt who betrayed Isildur.

I can't recall an entire army of elves being turned in a horde of walking dead due their cowardly betrayal, can you?
