obviously, this situation of if we don't benefit from it, eliminate it, is in the criminal world for the most terrible of criminals. the majority of people dont benefit from prisions rehibilation programs, old people dont benefit from schools, young people dont benefit from medicare but they still exist. for criminals have had truely commited the worst crimes, death is a fitting punishment for them. this logic i am using really only applies to those dangerous criminals; applying it to other place doesn't make since as you pointed out.The idea that "if we don't benefit it, eliminate it" is completely against true Christian ideals, and is morally repulsive. No one said that they necessarily need to be jailed for life. That may often be the case, but I feel that in cases of truly rehabilitated criminals, they should still be paroled.
Not to mention that the taxpayers are still being charged if we're killing the criminals. Lethal injections aren't cheap. (This is assuming we're not just using a noose tied to a tree branch)
the lethal injections are mostly potiassium, thats just a simple chemical.
