We shoot rabid dogs.
And we consider that a good thing to protect society. Never yet met a dog that was evil, some are just misunderstood or poorly socialized....
But this sleazeball we are gonna feed, clothe, and house, for the rest of his natural life.
Myself, I think we should hang him, in the town square, after reading the sentence and offering him any last words.
And televise it.
Then bury his body in an unmarked grave.
But then again, I am so soft with criminals it is disgusting.
(alternatively, a firing squad with the same disposal of his remains.)
