From novel spoiler, it’s mc's mother who is at fault (not 100%). But cause of that thier happy family fall apart.
And the father had so much to handle, eldest was at age where he had his own emotion so you can't blame it on her father. Furthermore the death of thier mother made jade the way he is now and her sister was manipulated so you can blame the royal family's every member cause their fault is at level w

Thank you for the info! it really changes nothing in my opinions. You mentioned that pretty much everyone else around is guilty of destroying the family, sure, that works. That still does not and will never justify his abuse towards her. she did nothing wrong. a child is not the scapegoat for their parents crimes. never

its someone's else who planned this, i believe it was the queen's brother who drugged both the FL's mother and the duke. The duke had no idea and just blamed it on the mother and he thought she was part of the queen's faction to destroy his family. So I do understand where the duke is coming from, but at some point, he should've done a better investigation instead of being blinded by hatred and rage and making olivia the recipient of his rage

Exactly! Also...He could've just sent her to another family or paid for her to have her own household. Or said she was the 'illegitimate' daughter of a distant relative. He had options.
I totally appreciate his resentment and anger, but as others have mentioned *SHE* didn't ruin his family. She was a child born out of circumstances out of her control.
Too often 'illegitimate' children were treated as if they had magically engineered their own creations and were trash. Rather than innocents of a usually shitty situation.
Imagine abusing your child, leading your wife to divorce, filling your kids with hatred and make your home a living hell, all because you couldn't keep it in your pants. That Mf father can get impaled on a stick drenched in poison and die slowly ugh I hate him so much
