Some children are parentified at a early age. Once this happens, they take on adult responsibilities in the family.
They feel like they drove the parent to it.
Oftentimes the parent will, whether directly or indirectly, guilt trip the child to make them think that it's their fault. Or the child will not see other outside factors that cause it, so they will blame themselves for it.
There is a host of reasons why this happens. If You read my hub where I have mentioned the development of mental apparatus, then you will be able to see where this may come from. Basically the superego becomes dorminant instead of the ego.In other instances,certain family or enviromental factors make these children take the role of the parent, hence there is a role reversal.
If a parent does nothing about it, it becomes almost irreversible, which is a selfish attitude of the parent. In other instances, the parent narate stories which make the children feel responsible for what has happened.To understand what really happened, you need to consider each case but can not generalrise.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
