An eye for an eye makes the whole world blind.
-Mahatma Gandhi
Needless to say, I am against the death penalty (and torture, castration, etc), and I find the airing and watching of Saddam's execution, as well as the various beheadings in Iraq, to be highly distasteful, and something of entertainment value only for the very lowest dregs of society (probably those who are not far removed in thought from the perpetrators of such crimes).
If, however, we can find no better solution than removing such individuals from society (and even then only for violent crimes), I think it should be done quickly, mercifully and with a sense of regret. To perpetuate hatred and feelings of revenge, particularly for someone you do not know and for something that does not effect you personally, is merely adding to the problem, and not very attractive. Actually, feelings of revenge for something that does effect you is not an especially beautiful way to live, either, though extremely difficult to overcome. Under this system, nothing ever changes, no one breaks the endless cycle of blood for blood.
What we need are enough mutual understanding and tolerance to keep us together and enough detachment not to become hopelessly entangled in one another and to avoid wallowing in our own and others' filth.
Revenge and hated seem to be the knee-jerk reactions throughout man's history, up to our current time, with kindness and forgiveness rearing their heads only with the periodic appearances of various wise men (Buddha, Gandhi, Jesus, etc) throughout the relentless march of centuries. How quickly their message is forgotten or corrupted to accommodate mankind's ridiculous need of blood. I feel man is fully capable of overcoming his "nature" but that a comprehensive effort at education has never been attempted. I am an idealist, but I do think it is possible. The pragmatists certainly haven't solved the world's problems, if anything they have merely complicated them and excused the old belief of survival at all costs.
