Human psychology is very complex but thankfully i have done enough years of basic studying into it to know the answer to this. Everybody has a different mental capacity to tolerate pain and trauma. Some are able to reflect on their own trauma to understand that what happened to them was wrong, and that nobody should go through what they did, and so they should never afflict anybody else with the same pain they went though. This phenomenon is called resilience; the ability to cope and bounce back.
Then there is the second way that a person can be effected by extreme pain and trauma. Post traumatic stress disorder as well as other less serious mental health issues are involved here, as a person can be emotionally vulnerable in this state. However, this is not the extreme effects of trauma.
The third, and extreme effects is what we are seeing with maya. Here, trauma can really have a devastating impact on a person, and can cause a psychosis. It can distort the way a person feels and thinks. The way a person socialises. The way a person acts and reacts. In such a situation, an abused can often grow up to become the abuser. This especially applies to early childhood trauma, as children learn through observation. This is why they say that the abused can grow up to become an abuser, because their view of relationships is so distorted, that they start to believe that what happened to them is a completely normal way of behaviour.
In maya's case, taking her mother, jhanvi into account, there is the strong possibility that it is not just nurture (environmental factors), but rather, also nature (biological, genetic factors) that can explain why maya's childhood experiences made her this way. It seems quite clear that like her mother, even maya does not have the mental capacity to withstand trauma, or be resilient. Like I explained, everybody is effected differently by trauma.
