I mean it sounds like she was a evil/terrible 'person' to begin with but her obsession with Victor brought out her worst qualities. I don't hate this.
But wtf is this time travel shit and why should she have any sympathy uuuuuuuuugh I do hate that.
Duke needs to quit being such a softy. Go back in time to before Sade cursed him and touch her so she dies of an ironic time paradox. It's no less than she deserves.
Uhh yeah I don't buy that reason. It's not that no one understood or loved her. She's already unstable before they met. Such a weak twist to not beat the shit out of the supposed antagonist.
