This is not even a remotely coherent "argument," on your part, in defense of a lessened sentence for the sociopath in question. (The only genuine "point," it advances, however inadvertently, is the pressing need to increase prison sentences for robbers and rapists; a premise with which none here have, or would, argue,)
It's a sick sick sick world that criminalizes puppy killing and legalizes baby killing.
False (and intellectually specious) "either/or" straw man, already long since discredited and set aflame, earlier in this thread. Go back and re-read, please.
