It's an interesting question. I tend to consider it *mainly* fault of the parents in some way... but, I don't want to seem like I am blaming the parents if they have this really difficult, uncontrollable kid... I have no kids, so I don't know what the circumstances might be that they have difficulty. But, I think if they are finding so much difficulty to control their kid, they ought to get some help or advice (I mean, maybe s/he have a medical condition like adhd?) If I had real problems with my kid I would be really worried and upset, I would be looking for help, not just to let the situation continue.
But, I was thinking there of 'badly behaved children', but I think you were talking about kids who actually grow up to be violent (I've gone off the point again!). Mainly I would say yes, there probably is some lack of awareness and failing from the parents because from the beginning they have responsibility of forming the character of the child... but of course it's a big responsibility and no-one is perfect; also maybe other things go wrong for the child that are outside control of the parents (bad experiences etc.) Also there is nature/nurture issue, that perhaps if there is certain tendency (in the brain) one way there's a limited amount that can be done about it (but my scientific knowledge about such things isn't good enough to discuss it really).
And, of course there may be people who become violent or anti social but they were ok as children but became like that later in life for another reason.
Hehe, generally I think I am trying to agree with you but making excuses too so that it doesn't look like I try to put all the blame on parents...![]()
