Several places have abolished the death penalty. However, I find that the death penalty is perfectly acceptable, given 100% assurance. I believe very strongly in the Law of the Old Testament, and does it not say "an eye for an eye"? If one takes another's life, should not their life be taken? Also, all "life" sentences should be changed to death sentences, except for the most heinous cases, in which case, solitary life confinement is a suitable punishment. However, we waste our resources and jail space with criminals who will never be reformed and released. I would give a number, but I can't find one. However, the death penalty should not be given to children or teenagers, only to adults, to prevent the execution of one who does not deserve punishment due to a lack of knowledge of depth of his actions. The death penalty should not be applied for life with parole, only life without parole, though (and life with parole should be used in uncertain cases).
I am for the death penalty because, quite frankly, life in prison is not only too long for a repentant prisoner, but provides too much chance for a unrepentant prisoner to escape.
