Heinlein once wrote that “an armed society is a polite society,” which has to rank among the stupidest things ever said. I’m fairly sure he had southern ancestry as well.
In an armed society, those with the fastest triggers, both emotional and physical, will thrive and survive. The Southern elite were a classic example of a decadent society on the verge of collapse. They had the most exaggerated notions of “honor,” "duty,’ “womanhood,” and “purity.” They were ready to fight to maintain those “ideals” at every moment. Psychologically, a war had to arise because there was no longer any way of maintaining these notions without dishonoring them in their own eyes.
The OPs question about why the North fought is the more interesting one, but the answers are not much more difficult. Patriotism is a very powerful force. War has always been idealized and glamorized in the stories told by the survivors. Emotions in the north had been stirred by every public political event since the Fugitive Slave Act. The war was mostly fought on southern soil - the couple of minor incursions at Antietam and Gettysburg horrified and panicked the north and sent enlistments soaring - so it was a distant notion, not something that devastated local farms and villages.
And the North was so much more powerful than the South that the war was fought almost as an afterthought. It was the only war in all history in which population increased because of immigration to the nation at war. The North gained more healthy male immigrants during the war than it lost in battle deaths. It kept growing stronger as the war lasted. No matter how many romantic notions people glurge about how the South almost won, the South never stood a chance unless the North abjectly surrendered, which had zero per cent chance of happening. The North had all the raw materials, the factories, the military supplies, and a huge edge on manpower. It was a slaughter, made less obvious solely because of the incredible bungling on the part of the first generals and the oddity of having to protect a capital that was for all intents and purposes surrounded by enemy territory.
The U.S. has won all wars since when these conditions held, and has lost all wars since when these conditions didn’t. We took the wrong lessons from the Civil War into the textbooks and patriotic propaganda. We’re just begin to understand how disgustingly awful antebellum Southern society was. The Glorious Cause was slavery and derangement. True American values won out over that. I don’t apologize for that: I revel in it.

It is probably wrong to say the South had no chance of winning. I don’t have McPherson’s “Battle Cry of Freedom” anymore but there is a passge where he says many European military experts thought the South would win: too much territory to effectively hold, too much costline to blockade. It has been suggested by some people that the decision by Lee, Johnston, Forrest and others to surrender and go home without engaging in a guerrilla war in April, 1865 saved us from years of insurrection. Aides to Lee who advocated this course noted it took Rome two centuries to fully conquer Spain after they beat the Carthigians. The Moors and later Napoleon never did. If Jefferson Davis had assigned better generals to the underappreciated Western Theater (see Victor Davis Hanson’s “Ripples of Battle” for a discussion on the circumstances of the deal of Albert Sidney Johnston at Shiloh), if Grant had been cashiered as a drunk, if the French and British had decided to intervene to weaken a potential Western Hemisphere rival, the South could have won despite fewer people and resources.
