On the contrary, if they were
wild men they would not appreciate the sun for its light and would hate it for its brightness. The same thing goes for
Gollum. Gollum is [almost] a
Hobbit and
hobbits don't hate the sun...yet Gollum does
It is doubtful as to whether or not any
men hated the sun. The Sun was considered as a sign for the awakening of men, even in BoLT, or the idea that the sun was a herald for the awakening of men, or even the latter conceptions on
Arda, in Myths Transformed it is seen as allowing men to finally escape from their 'besieged' land as it dries up the floods caused by
Manwe's winds. Therefore one can assume that men would have soem 'reverence' for the sun. Remeber, the Variags weren't
evil/corrupted in the sense that
Orcs or Gollum with
the ring were, they would've needed the sun in order to survive, like all other men. Just because they were 'wild' doesn't mean they were evil. Notice the village of possible
Sauron worshippers in Tal-Elmar, they weren't evil, and
Sam's thoughts about the dead Southron.
