They were pretty fly for some dead guys!
Anyway, the Ringwraiths weren't always scary bad-asses. In their former lives, they were "entrusted" with the seven Rings of Power that were given to mankind. Who would have thought that the power would corrupt them? Sauron, of course.
If you killed one, he'd spawn back to "life" in Mordor. His ride, however, would stay dead. So eventually, after their horses were killed, flying creatures were procured to help the evil war effort. Go, team, go!
