Answer:
Nurture
Explanation:
Human behaviour is a social perspective and hence nurturing has a pivotal role in shaping the character of a human being.
Nature however is more prominent in shaping physical characteristics of an individual.
The kind of social environment, learning, teachings, moral values, human values, and other social parameters to which an individual is exposed determines his/her nature.
For example - a child whose childhood has been very disturbing usually involve in criminal activities in his/her adulthood while a child who has been trained to behave morally will definitely behave like a gentle man or woman in adulthood.
