The point is that I don't feel like paying the money to feed, clothe, medicate, shelter and guard this maniac for 60 years. What's the point in keeping him alive? There's no question he's the killer in this case, so execute him and move on. Crazy or no crazy, he's just taking up space and precious oxygen on the planet. He serves no purpose living or dead.
And ness, you said execution costs more than a lifetime of detainment? Well I've never heard that, but if it's true, while we're talking about hypotheticals and wish lists, one of the nutbag's AR-15 rounds couldn't be more than a buck, could it? I'd say a couple bucks at most, right in his orange head, should do the trick.
