One can hardly expect an unbiased answer from convicted killers. Moreover, a fear of execution may well have been resident in their minds, only to be overpowered by other urges, stronger at the moment of their violence, i.e., hate, rage, greed, lust, etc. Every law-breaker knows there is the possibility he may be apprehended, convicted, and incarcerated. But it is argued that the legal system is so flawed that injustice frequently prevails. There are several biblical principles which, when in place, would make the death penalty eminently more effective than it now is.
Capital punishment ought to be administered with absolute fairness.
Neither race, money, influence, nor any other trivial factor should have any influence upon the facts of the case. If there is any doubt about a man's guilt, grant him the benefit of that doubt, and spare his life. In many cases, however, there is no doubt about the guilt of the perpetrator. There is no excuse for not demanding the full penalty in such instances. Punishment of the convicted murderer ought to be implemented speedily.
