Scaramouche is 6th fatui harbinger, he already got the gnosis and now he wanted to become a god, to show his creator that he is worthy to be a gnosis holder. But gnosis rejected him so dottore is making on him painfull experiments to make the gnosis stop rejecting him. But it's only getting worse and pain is getting bigger and bigger, he can't take it anymore, he don't want to feel pain anymore
