As we all know Jennifer Blake, o Julia Baccari, is the Darach. She has killed innocent people and called it a necessary evil. Her backstory is that she was Kali's emissary and was scarred and left for dead. She took a vow to get revenge on the Alphas for killing their emissaries and overlooking them. She's a villain. But unlike Deucalion, she actually genuinely cares for someone, Derek. While she is evil she could have potential to switch sides help Derek and Scott beat Deucalion.

Now there's Peter Hale, the well known alpha villain from season 1. He was nearly killed in a fuoco that killed his family. His excuse for killing his niece, Laura, was that it would give him power to get revenge on the woman who was behind his family's death. He killed other innocent people as well. He nearly killed Lydia and used her as a human puppet to bring him back from the dead. He mentally tortured her during season 2. He manipulated Derek into getting Ennis to bite Paige to turn her. Peter is allowed to work along side his nephew and Friends after he is brought back to life because he is weaker and not a threat.
