I think I've asked this question before but I don't know where I did. Anyways, I'll ask again. Why did the Dread Doctors go out of their way to kill their failed chimeras if they just let Theo steal their death cure and resurrect most of them (or at least half) anyways? I mean, even after La Bete was created, and after they found out Theo has a pack of chimeras, they still went out of their way to kill the Berserker chimera (still can't believe Scott and Stiles left him alone to get murdered). Any ideas on why they kill them?
