Yes. It won't stop until perhaps we decide to do what you said above where the punishment is exactly what the perp did to his/her victim.
As I have seen so many crimes currently, I have become less & less tolerant of sisters excusing brothers who kill by saying, "Oh, he was just getting his life back on track & going to school." Hogwash.
Responsibility...arrest the bad folks, try them and if guilty, isolate them from good folks and punish all appropriately. We can refer to it as 'regularfeller's response to cut recidivism rate of reprehensible radicals'.
