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?
Are we counting it as the age of majority? Murder a 15/17 year old, imprisoned for life, murder a 16/18 year old, regular sentence?
Rape an adult, life imprisonment, murder an adult, regular sentence?
