So we don’t need rapists (incl. of adults) or child murderers in society because they can’t be rehabilitated. But people who murder adults can serve their time and be welcomed back into society…am I following what you’re saying?
Apparently not. I said you have to look at the context of the murder to determine how to handle them appropriately. I even gave you an example of one where with mitigating circumstances. If it’s unlikely the murderer can be rehabilitated lock them up forever too. As for what’s considered a child I don’t have a good answer, I suppose again, it would have to be contextual.
