So does this chapter confirm that Mina is a psychopath ? (In the medical sense of course)

Maybe? To be honest I’m not sure. In the beginning she seemed to be more like an extremely depressed teenager but now we’ve been introduced to a past that shakes that. She could just have learned to act like a depressed teen from the boy who got beat up. She also learned from her father to punish bad guys. So maybe? No actually I’m gonna lean towards yes.

Maybe but she reminds me of Edmund Kemper in the thinking sense (though she doesn’t have any childhood trauma)
