I’ve seen a lot of discussion on how tragic Adar’s story is, but I don’t think I’ve seen any mention of how he actually realizes his mistake just before he’s killed. He tells Galadriel, “Adar is the name I earned. Help me earn it back.” I don’t know if people understand the significance of that second line. “Earn it back” means he realizes that he doesn’t deserve the name anymore, because he hasn’t been acting like a father to his children since this obsession with killing Sauron. That makes it all the more tragic, because Glug didn’t have to kill him. He was going to do things differently now. Atone for his mistakes. Stop sacrificing the Uruk in this violent crusade, focus instead on protecting them, defending their new home. But Glug didn’t know that—or didn’t care. That makes it so much sadder.
