i've got no clue on god, don't figure there's a way to tell, but belief in god or not doesn't directly mean i have to believe in afterlife or not.
and how is letting them live taking away life? there is a lot that they're allowed to do while in prison, not to mention the fact that, while prison isn't really the best life imaginable, its far better than being dead.
again, soo.... shoudln't the gov't not be allowed to arrest or imprison someone? in arresting someone, they're taking them against their will, which is kidnapping, and to then keep them in jail is holding someone against their will. those are both crimes, therefore, the entire prison system is defunct because its really saying, don't commit crimes because you'll be kidnapped and held against your will. oh the hypocracy.
to say that the death penalty is murder is to misapply the term. if your attitude is that death penalty is murder, (which is by definition unlawful and inhumane) and that you can't differentiate between the death penalty and murder, then how can one claim to differentiate between murder, capital punishment, manslaughter, self-defence, abortion, or euthenasia?
