Harry really wondered if he was a sociopath sometimes. He would feel no empathy for others unless he was emotionally connected with them.
Only if he loved or liked someone would he treat them as a human. Others were all objects to him, waiting to be played with. He felt no sympathy for the man. He kind of enjoyed watching him shivering with pain.
The man shivered and twitched for a while before panting heavily. An awkward silence hung between the system and Harry. Harry silently looked at the man suffering without any expression, while Catherine was seriously considering asking the king to stop the knowledge impartment process. The man was just suffering too much. That did not look normal.
