I'm saving this to use as ammo for all those who don't believe in capital punishment or revenge because, they say, they're not the "deterrent" everyone says they are. I always tell them . . . "Maybe not, pal, but the jackass executed won't kill anyone else." Then I go into the spiel that sometimes, although it might be the unChristian-like thing to do, revenge is salve sorely needed for the soul.
A worthy tag line...
