Why don't some parents realize that they're directly responsible for their kid's bad behavior?

@SW-User Possibly, but I think that their parenting is what needs to change, not their kid's existence. That just sounds too nihilistic to me

Not once the child is already born of course. But lazy parenting is such a huge pet peeve of mine and if you're not going to discipline and take care of your kids, don't have any. @Invisible
