That's not even one of Uglúk's faults

You are absolutely right. Yet this is what this thread is about - not about society, but about the individuals. And overthrow? That's not the way it works. If in some Fourth, Fifth, Sixth, Seventh Age the Orcs were to change their ways globally in a way that it could be seen, it would have to come some other way, slowly, from the inside.

But yet, as I said, this is about individuals - and I am by no means implying that these individuals could have had some major impact on the society simply as they were, although even this can be considered. But my main interest was to find what was in the individuals we know, try to get a more "plastic" view of them, and then eventually come up with something more based on this - which is of course welcome as well.

In case Tolkien didn't really make all up then that might be our source of vampire legends and other strange sightings.

They might be in the sewers of our great cities right now planning how to get back at us.

Actually, it is quite interesting to see how they are presented in different works.
In The Silmarillion as well as in The Hobbit they are presented as evil creatures with seemingly no possibility of becoming good.

Now goblins are cruel, wicked, and bad-hearted.

Also there are no examples of them showing any sign of kindness in these books as far as I am aware.

Whereas in LotR there are these few examples. From the discussion between Shagrat and Gorbag one can see that they could be friends (at least until they fight over something) as they planned living somewhere away from any masters to command them.
