For him to spend eternity in a locked windowless room alone with the sounds of all the crying children who were kidnapped/stolen/stripped out of their parents arms and all the parents who cried on a recording that plays 24/7 at high-decibel level? If it were loud enough he might become deaf in which case those sounds would be the last things he ever heard and would reverberate inside his head 24/7 till eternity ends which I believe would be never ever.
