@F_O_Khonshu its a cool theory i think it could make sense and it just depends on how the devils react when he's created I guess, I personally am still just a bit skeptical that a lone serial killer could create a devil that goes to be feared by all of hell
@F_O_Khonshu its a cool idea i do think you're onto something by saying hes not the actual devil of chainsaws (i havent consumed chainsawman medias in any big way) but if they do operate on fear who the hell is scared of chainsawmen enough even after a serial killer for him to be dat strong
