Generally, I don't believe in the death penalty.. The gubermint has proven that it can't be trusted to kill the right fella for any given crime 100% of the time.. So.. Screw those guys..
Having said that - with this one there is no doubt, so let's hope he dies screaming..
Also.. I wouldn't convict anyone - not one single person - who killed out of vengeance of a slain loved one, either.. So make sure that I'm on the Jury if you ever fall afoul of that..
My preference though, would be to either sling this douchebag into a room full of the victims kin (vengeance is theirs in my opinion), so he can be ripped to pieces as slow as they like, or bring back Breaking on The Wheel, 'cause shit's not getting through to some of these jolly-assholes..
I-mean, they give them tranquilizers and all but play "Music of the Mystical Rainforest" while they pump these fuckers full of drugs they'd bust me or you for, for being pumped full of.... BEFORE they pump the good shit into them that puts 'em down..
Breaking on The Wheel tho'
.. Now THAT's a Deterrent!
