I would like to introduce a new villain for the Pure Evil catagory. Introducing Alice Angel/Susie Campbell from Bendy and the Ink Machine
Who is she?
Susie Campbell is the almost actress for Alice Angel whose role was takin away. Joey cheats on her and this drives her insande. Later, she accepts an invitation from Joey to be part of an experiment, but the machine turns Susie into an abomination where "Alice Angel" gets her face twisted!
What does she do?
She tortures ink creatures and tied to extract ink from them and she recruits Henry, only to backstab him later via trying to kill him via elevator crash, all in attempt to become beautiful again. She experiments and legitimizes Boris by turning him into an ink-robot combo monster and sends it after Henry to kill him. When "Boris" is defeated, she gets so angry that she attempts to kill Henry up close and personal. She gets stabbed by the real Allison later on.
Moral Event Horizon?
She makes attempts on Henry's life despite the fact that he has nothing to do with getting fired. She also kidnaps Boris to be beautiful, convinces Henry to save Boris despite knowing it's too late and forces Henry to fight a brainwashed Boris. She then later attempts to kill Henry herself.
I'm honestly back and forth: TV Tropes says she's a Complete Monster while other viewpoints show her in a victim sort of light due to her multi-personality conflict.
