A child can’t choose who would be their parent. Every human being has right to reproduce and have kids. Look at this fact that every child is born alike biologically with equal potential but the initial days of being nursed at home, and extended parenting until the child learns to become independent provides impact on the child.
The child learns by mimicking their elders at home, what they see, they try to follow just like any other animal like a cub would learn to hunt for pray, a bird would learn to fly and catch insects, a baby monkey would learn to jump from one branch of a tree to another, similarly human babies also learn the attitude and behavior from their parents or elders at home.
Irrespective of the type of attitude, whatever the child will see in the early childhood will become naturally learnt and will get imbibed in the overall personality of the child. Now, when the child grows, parents compare their behavior with other children, who might have got better environment at home and surrounding, such parents try to instruct children to behave well and request school teachers to pay additional attention but until the child is taught moral science, value education and the environment is not changed, it is near to impossible to bring any good change in the child, except if any magical change doesn’t happen due to self realization or development of conscience. Yes, education can impact the outlook of the child but the core remains rooted with the family culture.
