Fontaine
Fontaine is one of those characters where the supernatural part of the story doesn't make him awful. He was already awful. The magic just gives him another way to hurt people.
He's the man who enslaved Elijah in Zombies: The Cursed, and Cassidy is his daughter. When he discovers that they love each other, he treats the whole thing as if something has been stolen from him. Cassidy tells him directly that she loves Elijah. He doesn't accept that she has made a choice. He decides she must have been bewitched, then keeps beating Elijah.
That attitude follows them after they escape. Fontaine calls for Reginald, who has the power to raise the dead, and tells him to bring up the sleepers. Reginald actually points out that Fontaine's own daughter is out there. Fontaine's answer makes it clear that her safety no longer matters to him. If she has chosen Elijah, he no longer considers her his daughter.
The thing I want to keep straight with Fontaine is how his control works. Reginald is the one we see actively using magic to raise the dead. Fontaine has a ring associated with controlling them. Those are related advantages, but they aren't the same thing, and the story doesn't establish that Fontaine personally has all of Reginald's abilities.
When Elijah finally confronts them with the Hunters, he understands that arrangement. He shoots Reginald and takes the ring away from Fontaine. Once both protections are gone, the dead close in on Fontaine himself. The man who was using them to chase Elijah and Cassidy suddenly wants Elijah to save him from what he unleashed.
It's a nasty ending, but it follows what we've seen of him. Even during the fight, Fontaine is still talking about Cassidy as if she belongs to him. He doesn't get to the point of admitting what he's done to her or their family. He just loses the power that was letting him keep doing it.
And the ring keeps affecting the story long after he's dead. Elijah comes back looking for it in the present because Cassidy is still at risk of rising. Fontaine's control is gone, but the damage doesn't disappear with him.
