Yeah, no we can still want justice and not want to be horrified by the act of execution for the rest of our lives.

Or, I don't know, perhaps we can crush parts of their body one at a time. Or maybe set fire to their limbs one at a time. I mean, why not?

(And never mind that if The State could, even once, execute someone who is innocent, it renders capital punishment instantly null and void in my mind.)
