Coward. China has capital punishment, which is plainly appropriate here. May he have a swift trial and the right judgement.
If you want to make a spectacle of your trials and tribulations, then set yourself on fire (self immolation) like the monks do. That'll get attention, and you only hurt yourself while drawing attention to your cause (as this madman had). Instead he kills small children and robs them of what they could have and be, and ruins 23 families forever.
Child killers/offenders are the worst...they're not even people.
