One who kills witches maybe? I don't know if he meant to say he was physically a monster but we already know that he is a mental monster of sorts.

I, for one, would really like to see if he turns out to be some sort of serial killer. And his attitude being "I kill them so I won't kill you." sort of thing and that's what Fiona senses in him. I read somewhere that evil knows evil, so I think it'd be an interesting side/main story
