I don't like my answer, but yes, I think conflict is natural in human societal interations, interpersonal interacations, and within each of us as individual humans.
Not because of some externally implanted "sin nature" but because the same characteristics which promote our suvival also promote our extinction.
We naturally strive to improve our lot in life: What I take is not there for you to take, whether it's money, land, resources, civil power, a mate... whatever. Scarcity is real, and so is desire.
We have differing talents and values: This is not all through culture and indoctrination. Even one family there may be both jocks and nerds. Hands on active doers and builders will never see entirely eye to eye with theoreticians and planners. What is an exciting adventure to one person is a terrifying ordeal to another.
We are natural coallition builders: Humans are tribal. When we form a new idea, we instinctively seek to find others who share it, or who can be convinced that it is right. But since we have differing natures (see paragraph above) we find some people who don't take to our idea, and those people form their own competing coallition because:
We are naturally defensive: When we find that there are a bunch of people espousing some idea which feels wrong or dangerous to us, when we feel outnumbered, we respond by seeking out our own group--those who will stand with us so we can say, "I am not wrong. I am not insane. Look at all of the people who share my view." We need this so badly that we are willing to overlook huge areas of disagreement in order to stand together against the "other". Obama and Wright. McCain and Hagee. The Zionists and the Apocalypic Christians. The enemy of my enemy is my friend until our common enemy is defeated.
Due to our basic biology, our bodies respond to conflict by flooding us with agression-stimulating drugs. Enough agression leads to fighting. Big groups fighting is called war.
We can and should seek to restrain ourselves, individually and societally. We can and should seek peaceful solutions to disagreements and conflicts. But no, I don't think humans could be humans, or could even survive as a species, without the same characteristics which make conflict, and yes, violent conflict, inevitable.
