Roots of abnormality

The roots of mental abnormality of criminals are hidden deep in their childhood. Actually, it is common for any psychological disorder of people. As we are in our childhood we sharply percept everything we see, and even the tiniest stuff may greatly strike our imagination and influence our psychic. Such vivid emotions we undergo will never be replaced with other emotions or forgotten.
Say, if a child sees his father always hurts his mother, such kid will be sure that such attitude towards women is okay and there is no need to treat them in another way. Even if one will try to change it he or she will fail to do that. The experience child has is more vivid and striking than any pronounced word. Nothing will change that thought except another, more intensive shock.
It is also common that mental abnormalities are resulted by breaking of beliefs child had. Say, there is a child and it has its own believes. Those beliefs are foundations a child will base its entire life on. Though, single evidence can prove a child that all the beliefs he or she had are wrong. The contradictions of beliefs one had and beliefs revealed for him by real life will result in defection of morality.
It is also common that children lose their belief in justice in their very childhood. That may be resulted by unfair attitude towards a child. A child knows that he or she did nothing wrong but other people don't trust him. Soon kid will get tired of proving his right and will realize that there is no need to be fair as one way or another people don't trust him. Once child realized it – a criminal is born inside of him.
