A morality system would be cool it can work like this
"Say your a certain rank class of a demon slayer right? What if. And hear me out. What if Everytime you do something wrong as demon/slayer you loose morality points? Say your a hashira.. if you kill 30 demon slayers/civilians you loose morality and if your morality goes to 0 certain NPCs will deny talking to you or offering help for weapons etc.. the only way to get morality back as a slayer is to kill demons/do good deeds.. same with demon players if you fail to complete task given you loose morality negative morality makes every demon in a 10 meter radius attack you and demon npcs will deny working/giving you quest and has muzan kill you every time you try to talk to him with his dialogue being:
"You are a disgrace to our kind. Mediocrity is not tolerated. Redeem yourself or face the consequences. Weakness is an affliction I do not abide. DIE!"
The only way to get morality back is by killing slayers or whatever you guys want
