To kill someone for committing murder is a punishment incomparably worse than the crime itself. Murder by legal sentence is immeasurably more terrible than murder by brigands.
If you want to be a grocer, or a general, or a politician, or a judge, you will invariably become it; that is your punishment. If you never know what you want to be, if you live what some might call the dynamic life but what I will call the artistic life, if each day you are unsure of who you are and what you know you will never become anything, and that is your reward.
Exemplary people concern themselves with virtue,
small people concern themselves with territory. The ruling class
thinks of punishment, the lower classes hope for benevolence.
There are limits to the smiles and scowls of diplomacy. Armies and missiles are not stopped by stiff notes of condemnation. They are held in check by strength and purpose and the promise of swift punishment.
I personally have always voted for the death penalty because I believe that people who go out prepared to take the lives of other people forfeit their own right to live. I believe that that death penalty should be used only very rarely, but I believe that no-one should go out certain that no matter how cruel, how vicious, how hideous their murder, they themselves will not suffer the death penalty.
