Yeah same thoughts she suffer enough to hate the people she once trusted, her mother was humiliated to death because of a mere concubine.
I understand that what her mother did is bad but the hatred and betrayal that her mother felt when the emperor choose a concubine over her must be really hurt that she didn't think anything but revenge that result execution.
But think guys she lost her mom at young age got humiliated by a step mother who cause her mothers madness and execution.
That's why i understand if she's being hateful of him
