Arcane Topic Warning: Part the Third

but I'd say that greed is their worst sin/trait/fault.~Thinlomien

For 99.9% of the dwarves, I agree, but then we have Gimli...

'No you do not understand,' said Gimli. 'No dwarf could be unmoved by such loveliness. None of Durin's race would mine those caves for stones or or, not if diamonds and gold could be got there. Do you cut down groves of blossoming trees in the springtime for firewood? We would tend these glades of flowering stone, not quarry them.'~The Road to Isengard

'But if hope should not fail, then I say to you, Gimli son of Gloin, that your hands shall flow with gold, and yet over you gold shall have no dominion.'~Farewell to Lorien

So, I've always wondered, what makes Gimli different from the rest of his greedy dwarf brethren? Or are there more dwarves like Gimli where gold and riches hold no influence over them?
