Ok so i also read the spoiler.......
So apparently she gets pregnant again. And the emperor hearing this becomes a b*tch and sends(plans to??) her other kid to an expedition. She goes mad crazy over it and goes to MC's dad and blames him, asking if he's happy that She's suffering. And later she almost loses her baby in womb but MC saves them. Later her first son also loses all respect to her. In the last moments, the emperor orders her to kill common folks to which her current husband tries to convince not to. Ofc She's a b*tch and doesn’t listen so the current husband takes the son and the newborn and runs away leaving her. She spirals and later is executed.

She doesn’t deserve to be a mother. Sacrificing your own daughter whom not only you didn’t raise, already tells what kind of an animal is she.
.. she deserved her end based on spoilers.
