Why does Thorin refuse to share the treasure with the men from Lake-town?
a
because they did not help when they came on the quest
b
because they killed Smaug
c
because he has caught his grandfather’s greed
d
because they are allies with the Elvenking
If you had read the books or watched the movies, they both explain very clearly that Thorin is overwhelmed by greed when it came down to the treasure in the mountain. So, the answer would be C, Because He has caught his grandfather's greed.
