Are orcs actually evil?

[Sauron the White]

from A Little Green

The moral values and upbringing methods in an orc society differ much from what we call acceptable or normal or good. In the same manner a human child (hopefully) learns from his surroundings that killing and hurting others is wrong, an orc child learns that it's right. The surroundings from which an orc child learns are originally created by Sauron or Morgoth or whoever, and repeated by other orcs around the child because they have been brought up the same way. Similarly the children of the free peoples are, I would think, taught to hate orcs.

Its the lack of public education for little Orclings. They were all home schooled and truly believe that they are the center of the universe.
