YES. Thranduil has been through a LOT. He witnessed the loss of his father Oropher and 2/3 of his kin in the Battle of the Last Alliance, and he unexpectedly became king of Mirkwood and has endeavors to rule his people well ever since. His wife was killed by Orcs, so he basically raised Legolas by himself. The Dwarves won't give his wife's necklace back. He fears Sauron and Orcs, yet fights against them 2x (3x if you count War in the North in the books). Thranduil is so brave and strong!

The reason the Elves didn't help. It's so sad. Thranduil was not a coward or a traitor to Thorin, though it may appear so in the movie. He was doing what he, as king, thought was best for his people. He couldn't risk that many lives again.
