Rowling's Goblins = Tolkien's Dwarves?

[Sir Kohran]

Rowling's goblins are an interesting lot; they're somewhat ambiguous in their nature. Griphook is the most developed goblin we see, and he doesn't come across very well - he relishes the idea of pain in lesser beings, and (trying not to give out spoilers here) is also quite selfish and arrogant. However, he's noted as being a sort of extremist so it's difficult to tell exactly how indicative he is of goblins overall.

There are other goblins mentioned, some good and some bad. Gornuk accompanies the rebels, but another also reports back to Voldemort.

In comparison with Tolkien's goblins...I think Rowling's are perhaps what Tolkien's goblins could have been if they had developed and become civilised.
