Our laws and criminal justice system should lead us to higher principles that demonstrate a complete respect for life, even the life of a murderer. Encouraging our basest motives of revenge, which ends in another killing, extends the chain of violence. Many victims' families denounce the use of the death penalty. Using an execution to try to right the wrong of their loss is an affront to them and only causes more pain. For example, Bud Welch's daughter, Julie, was killed in the Oklahoma City bombing in 1995.
Vengeance is a strong and natural emotion.
But it has no place in our justice system. The notion of an eye for an eye, or a life for a life, is a simplistic one which our society has never endorsed. We do not allow torturing the torturer, or raping the rapist. Taking the life of a murderer is a similarly disproportionate punishment, especially in light of the fact that the U.S. executes only a small percentage of those convicted of murder, and these defendants are typically not the worst offenders but merely the ones with the fewest resources to defend themselves.
