No, the Confederates were trying to stop their property from being seized without compensation. Their property was human,
however, and
because of that I think that liberating the slaves justified the war.
Really? Attitudes like that ignore the fact that several areas tried to counter-secede and that many did not own slaves. One of my own ancestors was shot by Union troops who raided his house looking for honey, why did they need nine shots between four soldiers?

Thanks, you'll forgive me for deciding that your opinion is both ignorant and baseless. Attitude like this prevent me from seriously thinking about moving out of the old South and border states, and unfortunately even in the professional world this type of ignorance can be pervasive.
