I didn’t like her character (“mwahaha I’m so evil and smart, I’m such a villain, aren’t I?”) up until we had the episode where she was sent back to the mirror universe and she became repulsed by having Kelpian slaves/eating them, and, well, her old life in general.

Up until that point she thought seeing the prime universe hadn’t changed her. She thought prime universe humanity was weak because it sought power through cooperation rather than cementing themselves as the one absolute power. Going back and seeing her universe again through a different lense completely shattered her previously-held perceptions and beliefs. It suddenly dawned on her that she was wrong all along, and was ready to admit it and to make a change in her life.

Finally we had some depth to her (I’m sorry, “I’m evil but I love Michael Burnham because she’s the flawless main character” is not character depth), but then they ended her story.
