Wow...you would advocate executing a 10 ten year...
Seriously?
Would you sentence him to prison until he reached the age of 21, and then release him?
Would you give him a sentence of 20 years, and then parole him after 10?
Would you feel safe if he moved next door to you?
I'm not convinced that he will ever be anything but a threat to society.
Yes. Why not? If he’s old enough to kill in cold blood, he’s old enough to die for his crime. They charged him as an adult, and he knew what he was doing. He hasn’t been declared insane, so why is there an ethical objection to this?
