Do dirt bag parents realize their approach to parenting dooms their children to be dirt bags?.?

As I look at children as young as 4 or 5 it becomes clear even at that age which are going to have a delightful life, grow up well adjusted successful people. It also becomes clear which are going to be dysfunctional deadbeats that perpetuates their ways on their children. Do these people see what they are doing or are they oblivious to the damage they are inflicting on their own children?
