Both my wife and I agree--having our little girl gives us a slightly more "down" look on this sort of thing.
How 'bout this for an execution: First, start a good bonfire close to a gallows. Then, hanging, but not a far enough distance to break the neck, to about ten seconds after she loses consciousness. Cut her down, and stretch her limbs out so she's spread-eagled. Revive her. Then, cut out her guts, and throw them onto the fire. Make sure that she sees this in her last moments. Then, behead her, and quarter her. Take videos of the event. Play said videos over and over . . . .
