LotR -- Book 1 - Chapter 02 - The Shadow of the Past

[Mirkgirl]

Being a bit more practical (or cynical) I always saw that pity/mercy repays. Whether in straightforward sense or the higher power intervene (Gollum helping them find the way and destroying the ring at the end) or simply it makes you feel good in your skin and thus less vulnerable (Bilbo and the ring). However it's just a matter of opinion I guess.

The reason for this post is a lot more trivial... I just wanted to post one quote which is from the other end of the book (exactly the second chapter from back too), but still, I believe, belongs to be discussed together with this one.

from "The Scouring of the Shire"
- No, Sam! - said Frodo. - Do not kill him even now. For he has not hurt me. And in any case I do not wish him to be slain in this evil mood. He was great once, of a noble kind that we should not dare to raise our hands against. He is fallen, and his cure is beyond us; but I would still spare him, in the hope that he may find it.
Saruman rose to his feet, and stared at Frodo. There was a strange look in his eyes of mingled wonder and respect and hatred. - You have grown, Halfling, - he said. - Yes, you have grown very much. You are wise, and cruel. You have robbed my revenge of sweetness, and now I must go hence in bitterness, in debt to your mercy. I hate it and you! Well, I go and I will trouble you no more. But do not expect me to wish you health and long life. You will have neither. But that is not my doing. I merely foretell.

Do not kill when it's not needed. It doesn't mean be weak and let your enemies harm you, it simply means do not kill for the sake of revenge only. Also we understand that even revenge can be sweater with the enemy alive
