Death is less bitter punishment than death's delay.

Delay is a great procuress

At times it is folly to hasten at other times, to delay. The wise do everything in its proper time.

Any kind of death sentence is cruel. It doesn't matter what kind of death, I think the psychological punishment of knowing you're going to die is cruel.

Death is not only an unusually severe punishment, unusual in its pain, in its finality and in its enormity, but is serves no penal purpose more effectively than a less severe punishment.

As long as you have capital punishment there is no guarantee that innocent people won't be put to death.
