A lack of empathy can show some signs of autism. I have a hub on this that might help you decide whether your child may be ASD:hubpages.com/hub/Do-You-Think-Your-Child... course, if there are no signs of this, children's behaviour can be a bi product of their environment. If a child knows nothing but hatred, he will be hateful.
If a child is shown meaness, he will be mean. If a child knows and is shown a world of love, he will have the ability to love. The key, here, is be a loving role model and, in time, love's ability will win through.
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.
