The Hobbit: 10 Dumbest Character Decisions
10. Thorin Assumed Azog The Defiler Was Dead
This is technically less a decision and more an assumption, but it is still more than stupid enough to earn a place on this list. Thorin didn’t exactly cover himself in glory throughout the Hobbit trilogy, and this is just the start of it.
During the battle between Dwarves and Orcs, in which Thror was killed and Thorin earned the name Oakenshield, the latter engaged Azog the Defiler in combat. The Dwarf was on the ropes for most of the fight, but in the end managed to cut the Orc's hand clean off his arm. His troops dragged him away from the battle, and the Orc army broke.
The way it is portrayed in the movie and the flashback, this was the last Thorin saw of Azog. No major injuries but for the loss of his hand, and the Dwarf prince just decided that his enemy had died, like there was no other possible outcome. No need to see a body or anything.
There was absolutely no reason to believe that Azog was dead, yet even when he was told the Pale Orc lived many years later, he still didn’t believe it.
