cmv: The Uruk-Hai Berserker was the most courageous character in Lord of the Rings.

A warrior who knowingly sacrifices his life to kill the enemy may objectively be considered brave or courageous, whether the cause was morally just or not. The Uruk-Hai Berserker sacrificed his life for his cause, and watching that scene by itself, without any context, he appears to be acting heroically.

He was a trained warrior who was given advanced orders of a planned attack, and he willingly followed them, putting himself in a lethal situation. Knowing that the bomb he was carrying would take his life, despite being arrow-shot multiple times, he never wavered and never hesitated until his mission was completed successfully. 

No other character in the trilogy exhibited this level of selfless courage.

Many characters exhibited bravery, and Gandalf and Borimir both went down in battle, but the key difference is that they all fought knowing that they had a chance of surviving. The Uruk-Hai Berserker accepted a mission where his death was certain.

The berserker was raised from birth(?) to die in battle. If not in a suicide mission, then in a more conventional frontline battle. That's all it had to look forward to - even the Mordor orcs had a level of independence that led to the handful of them talking about ditching Sauron and going into the world to do orc things on their own. The Uruks, on the other hand, were built for war, physically and mentally, in the name of a greater power. If something's self-preservation instinct is that degraded by nature and by conditioning, can anything it ever does really be said to be brave?

Compare and contrast any of the hobbits who were on the quest. They're farmers. Frodo was looking forward to another fifty-eighty years of hanging out in the shire, eating good food, smoking pipeweed, and maybe pranking the Sackville-Bagginses with Bilbo's funny magic ring. He gave it up for a mission he had no reason to believe he would survive and then persevered even once that became certain - he couldn't have known the Eagles were coming.
