hmmm, sure i've seen a lot of messed up shit but what is he gonna do to the guys, is he going to put them through torture as in pain or mentally scar them, or turn them into girls and just expand his already, "SS-Rated Harem"
tbh they are a good match, combat wise, someone who can make extraordinary weapons and someone who can upgrade that extraordinary weapon into something that's capable of striking fear into the hearts of enemies who merely get scratched by it.
so either hes trash who doesn't want to leave his toy or he's scum but also kinda a normal person who doesn't want their friend to die either way he's still scum from all the shit hes done to him
