And the parents (or in many cases sperm donors), should also bear at least some of the responsibility.
I don’t want to go there. I put the LEGAL responsibility solely on the perps. Thing is, good parents can have bad kids and vice versa. I don’t want my government getting into that quagmire. I want it simple. You do it, you are responsible. If you didn’t do it, you are not, unless it can be proven in a court of law that you put the person up to it (e.g. paid the hit man to do it).
