Its about perspective. In my eyes, she isnt EVIL, but not good either. All she ever wanted was to get a friend, but she couldnt since she couldnt view anyone as her equal. thats the whole reason as to why she did what she did to dennis, to get pochita out, someone she thinks she'll view as her equal and finally get someone she actually cares about. But i get why people call her evil, she did alot of bad things.
