“Kaladin's father had once laughed at his son's desire to go to war. Indeed, now that Kaladin had decided he would become a surgeon on his own terms, his thoughts and actions of earlier years seemed childish to him. But Lirin thought Kaladin incapable of killing. You can hardly step on a cremling without feeling guilty, son, he'd said. Ramming your spear into a man would be nowhere as easy as you seem to think.

But his father was wrong. It was a stunning, frightening revelation. This wasn't idle fancy or daydreaming about the glory of battle. This was real.

At that moment, Kaladin knew he could kill, if he needed to. Some people - like a festering finger or a leg shattered beyond repair - just needed to be removed.”

“Deserves it! I daresay he does. Many that live deserve death. And some that die deserve life. Can you give it to them? Then do not be too eager to deal out death in judgement. For even the very wise cannot see all ends.”
― J.R.R. Tolkien, The Fellowship of the Ring
