Shang is a Sociopath (someone who shuts off their emotions as a response to trauma but can still show signs of emotion and has hope of recovering them) KSD is a Psychopath (Someone who was born without empathy and/ or emotions in general. Zero emotions ever.)
Some how him being nice is more terrifying than if he just straight up didn’t have emotions but I guess this is the kind of personality you get with a duel death and life affinity
