Contradiction.

So, I believe it was Aristotle, one of the dead Greeks, who said that 'man is a social animal.' I would definitely agree with him for the most part in that, aside from a few exceptions, this is true. Although, I would also like to say that often, mankind does things that are contradictory to this statement. . A man needs a woman in order to have kids, and a person needs friends for allies at the very most primal level. And being comrades with others entails that one entails a certain level of trust, and that they all depend on one another for aid to an extent.So why would it be seen that some people refuse to seek the counsel of one's friends and when confronted with a problem, often tries to deal with it by themselves and not seek outside help and treat it like a sort of shame?


Should beings who are actually social and interdependent seclude themselves? Or is there another force at play?
My theory is that this is society at work. Society in my opinion holds a very different nature than human nature. In the western society, individualism is cherished and I think that interdependence is looked down upon. Thus proving that society can be incompatible with human nature. 
If humans are social animals, then they must form societies, but if societies then counteract what human nature is, would that not cause a great psychological contradiction in someones head? So could it be that our drive to form societies actually is a bit self destructive?
