Good evening.
Don't be silly jake. Of COURSE I wouldn't sanction the execution of children. I'm the mother of two myself, and unfortunately, I HAVE a son who's mental age is less than that of his years. If it turned out that he committed a crime of the magnitude described above, I'd be heartbroken, but he doesn't suffer with schizophrenia, and is a very kind and loving boy. We love him dearly, and instill the best of values into him.
However, if he - or anyone else - turned into a serial murderer, then I would question the reasons why for the rest of days and hope that there'd be some form of treatment, but I still agree that certain crimes warrant the death penalty.
It's each to their own opinions, and I'm certainly not alone in this.
Finally, to daffy - I respect what you've said, but killing this particular man, as you put it, WOULD serve a purpose to society. We'd have one less mass murderer to pay for, and one less for the psychiatrists to try and work on to no avail.
