Exactly! It drives me insane that this is often justified in Asian culture. Parents are god and can't be wrong. And if I dare disagree with this, I'm the unfilial and ungrateful child. I mean, gee, I really should be grateful for all the cuts and bruises my parents gave me for getting a 96 on that math exam. Or threatening to abandon me by the street because I got a 91 on that science exam.
Please be Proud of yourself for standing up to their abuse, and leaving. You successfully escaped, don't ever let them or anyone ever manipulate you into 'guilt' if they are saying they are 'hurting'... If they were abusive, their 'hurting' is just their own selfish needs not being met, and if that package comes with abuse, then you have every right to say NO More.
I find it bizarre that abusers are typically narcissists who will torture their victims, yet when victims say they just finally can't take anymore abuse, suddenly the abuser claims to be 'suffering' from the absence of their prey. What about all of your suffering?
It's also not your job to help them 'learn'... if they create damage, you have zero obligation to them.
All of the above I had to learn the hard way, especially with my abusive father all of my life.
