Is our behaviour, both as individuals and as a species, governed by social constructs or biological traits?
It is a mixture of both nature and nurture. It’s been proved that certain DNA strands are responsible for anti-social behaviour. But they are only triggered when they meet the criteria that dis functional nurturing has. For example, out of 10 persona, say 2 will have the DNA responsible for Psychopathic tendencies, but if one is raised in a loving, caring environment then they will probably grow up as with no psychopathic tendencies, the other if brought up in an environment of abuse is more likely to become a psychopath. Of course these are rough guidelines. You cannot put a rigid structure on the growth of any individual, but you can make predictions based on large groups.
