No sense killin' the guy. It'll just empower him in the minds of a lotta people and make him a martyr. I ain't particularly in favor of capital punishment, cos you don't end evil by imitatin' it. You kill someone face-to-face on a battlefield where the odds are even, that's one thing, but killin' a prisoner who can't defend himself or fight back is just plain, outright murder, and it ain't justified. Never. And just cos he did it do someone else, that don't make it right for you to do it to him. Murder is murder. You can't get around that. If you don't like it, don't do it.
