Worn with Sorrow and Toil

[Angelalex242]

While that did happen to Hurin, Hurin was face to face with Morgoth. Ya know, that guy who made Sauron his #2. The guy Sauron learned all his evil from. The Sidious to Sauron's Vader.

Still, in the third age, a direct encounter with Durin's Bane or Sauron might do this. Corrupted Saruman is also capable of this, as he can basically talk people into being weary and miserable (qv. Theoden)
