Did you read the Declarations of Secession?
If I get what you're trying to say, slavery created the political schism that eventually led the southern states to secede, but it didn't start the war. The war was started when the Union failed to recognize the Confederacy's boundaries by refusing to withdraw from Fort Sumter.
Despite the fact that Lincoln didn't get any electoral college votes from the southern states, he still managed to win the election, because the population of the South wasn't large enough. Technically, since they weren't represented, I think they had every right to separate.
I don't know if modern society would be any better had the war not been fought (in fact, it could have been worse - in all likelihood we could have two countries recognizing slavery instead of one without it), but I don't think the ends can ever be used justify the means.
