I have theory, that still doesn't justify the boss actions but MIGHT explain them
what... and hear me out, what if he's bipolar??? and he has 2 personalities coexisting in one body, so the kind one is him all estable and in control
but when the switch get flipped, the other him comes into game and he's rude and sadistic
that's why he seemed surprised when daejong fainted after being choked because he didn't remembered doing it
