You know what? It was like there was this secret 15th entity called let's hate jon and everyone was its avatar one way or another? Especially in season 4.
Like yeah jon died and turned into a monster yada yada, but Melanie literally goes around stabbing people that piss her off? What puts her in a different category than Daisy or Jon who would literally starve or fade if they stopped doing their evil shit?

And I think that was the point of season 4 tbh. The line between human and monster is blurry even in real life, now imagine you add freaky fear powers to the mix.
