He who is dissatisfied with himself is continually ready for revenge and we others will be his victims, if only in having always to endure his ugly sight. For the sight of the ugly makes one bad and gloomy.
Teller contended, not implausibly, that hydrogen bombs keep the peace, or at least prevent thermonuclear war, because the consequences of warfare between nuclear powers are now too dangerous. We haven't had a nuclear war yet, have we? But all such arguments assume that the nuclear-armed nations are and always will be, without exception, rational actors, and that bouts of anger and revenge and madness will never overtake their leaders (or military and secret police officers in charge of nuclear weapons). In the century of Hitler and Stalin, this seems ingenuous.
The weapon of suicide bombing is so desperate that you aren't even left with the possibility of taking revenge or punishing anyone; the terrorist is killed along with his victims, his blood mixing with theirs
Tell a scoundrel, three or four times a day, that he is the pink of probity, and you make him at least the perfection of "respectability" in good earnest.

I'm a fighter. I believe in the eye-for-an-eye business. I'm no cheek turner. I got no respect for a man who won't hit back. You kill my dog, you better hide your cat.
Why seeketh thou revenge, O man! with what purpose is it that thou pursuest it? Thinkest thou to pain thine adversary by it? Know that thou thyself feelest its greatest torments.
But your mind is warped by an innate principle of general integrity, and, therefore, not accessible to the cool reasonings of family partiality, or a desire of revenge.
