The point of the system is to remove threats from society. It should be long enough such that the person will never pose a threat to society again. Justice was served in this case.
thats one of the purposes. As usual Judges are not as dumb as people think. There are plenty of people who have commited crime who are exceedingly unlikely to commit it again (most murderers have a lifetime average of 1). There are more factors, punishment being one.
i don't why this is downvoted. it seems pretty logical to me. if someone commits a crime and then goes to jail, they can't commit the crime again, right?
