I'll ignore my initial impulse to balk at the gender emphasis, as "society" has placed the "father-son" relationship on a ridiculous pedestal.
My specific answer to your question is this: a CHILD owes to his/her parent exactly the reflection of their upbringing. If it was filled with love, sacrifice, communication, fairness, *MODELLED* responsibility and manners and civic (NOT patriotic) participation and all that, then the grown child is almost certainly going to reflect back the humility, gratitude, and example of which his/her parents can be proud and to which they can be endeared.
If the kid was ignored, neglected, abused - if the parents were tyrants, selfish, mean, insensitive - hey - the kid owes them NOTHING but contempt. But - he owes HIMSELF the chance to have a happy, successful, fulfilling life by harnessing whatever support and inner strength he can to become the person GOOD parents would have raised - NOT for their sorry asses, but for himself.
Andy deserved Opie. And Homer deserves Bart. I'd try to cite real life examples of rotten parents having raised rotten people - but I can fathom no causal examples from memory, and I'm not inclined to depress and anger myself by finding them.
The author of "A Child Called It"? He turned out okay, at least according to his books. I can't get past the first couple of pages of the aforementioned book without wishing his mom alive again so that I could do to her what he was more than entitled to have done had he not been sorta rescued and then followed a rigorous and strong path. I cannot articulate the carnage, abuse, disrespect, defacation, hatred, and mortal anger that he was certainly entitled to have given his mother, the utter and total spiritual and bodily humiliation he was more than entitled to have subjected her to given the ....
I've never met her and I loathe the filthy bitch and seethe everytime I happen to think of her selfish and gratuitiously and SHOCKINGLY humiliating and dangerous abuse.
Anyway - my point? Karma. No one - of any authority or from any social strata is "entitled" to respect or deference by virtue of their position - and that includes teachers, judges, cops, clergy, "yer elders" - ANYONE - unless they ARE indeed decent human beings.
You act like an ass, a brute, or a bully - then you deserve "EJM" - whatever means your victims feel like taking to accomplish just ends, ARE just.
