When a human being is born, they are born with some inherent qualities that are critical for their survival. For instance, a baby is born with the ability to cry in order to get their needs met by another person. This is because the baby indeed needs another person to cater to them because they are too little to get anything done on their own. As such, a baby will cry when it needs to be fed, cry when it needs to sleep, cry when it needs comfort...cry for just about anything. Nobody trained this baby to cry--it is a survival tool it came with straight from the womb. If the parents of this baby do not set particular boundaries as far as responding to the baby’s requests, the baby learns that it can get just about anything by crying. This is how manipulation begins. That is not to mean that parents are solely responsible for the breeding of manipulators. While parents contribute to the development of manipulative behavior by virtue of genetics and the kind of nurturing, or lack thereof, provided to offspring, there are other factors at play. At the very core of our being, we are selfish beings. We want the best for ourselves first, and others later. For some people, there is a line as to what extent they are willing to go to get the best for themselves. For others, the line is blurry and sometimes even non-existent. Where the line is blurry or does not exist is where dark psychology begins.
