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
Cowardice is impotence worse than violence. The coward desires revenge but being afraid to die, he looks to others, maybe to the government of the day, to do the work of defense for him. A coward is less than a man. He does not deserve to be a member of a society of men and women.
Getting inside the mind of a terrorist wasn't difficult at all. Even as children, human beings fabricate elaborate revenge fantasies. We're not a particular species. Check out popular video games.
There must be what Mr. Gladstone many years ago called a blessed act of oblivion. We must all turn our backs upon the horrors of the past. We must look to the future. We cannot afford to drag forward across the years that are to come the hatreds and revenges which have sprung from the injuries of the past.

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.
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.
I call Christianity the one great curse, the one great intrinsic depravity, and the one great instinct of revenge, for which no means are venomous enough, or secret, subterranean and small enough - I call it the one immortal blemish on the human race.
Revenge in the hands of your enemies is a loaded gun. You can beg them for mercy, wave the white flag of surrender, but the only true elixir for the vitriol they bestow is a measure of hatred dispensed of your own.
A material resurrection seems strange and even absurd except for purposes of punishment, and all punishment which is to revenge rather than correct must be morally wrong, and when the World is at an end, what moral or warning purpose can eternal tortures answer?
