In my opinion, I think Katherine is not that cruel. I think she was just doing all that rebellious things because she was running from Klaus and she just wants a Family. And I don't blame her because became an orphan at the age of i think 17 or 18? like her whole family was killed. And her daughter, Nadia, was taken away from her as well. So I think Katherine deserve so much better. What are your thoughts about Katherine? Comment below.
