“Sam's hand wavered. His mind was hot with wrath and the memory of evil. I would be just to slay this treacherous, murderous creature, just and many times deserved; and also it seemed the only safe thing to do. But deep in his heart there was something that restrained him: he could not strike this thing lying in the dust, forlorn, ruinous, utterly wretched. He himself, though only for a little while, had borne the Ring, and now dimly he guessed the agony of Gollum's shrivelled mind and body, enslaved to that Ring, unable to find peace or relief ever in life again. But Sam has no words to express what he felt.”
