OK, how about this one then?
War is the remedy our enemies have chosen. And I say let us give them all they want; not a word of argument, not a sign of let up, no cave-in until we are whipped - or they are. -- William T. Sherman
War was the path that the south chose to follow in April 1861 and it seems to me that for them to complain about the damages done is the height of hypocracy.
A few posts up you asked why Davis was a fool. Well a big reason for that was he ignored the advice of his own cabinet and started the war at Charleston. His own secretary of state gave him the following warning:
Firing on that fort will inagurate a civil war greater than any the world has yet seen...At this time it is suicide, murder, and will lose us every friend in the North...You will wantonly srike a hornet's nest which extends from mountains to ocean, and legions now quiet will swarm out and sting us to death. It is unnecessary; it put us in the wrong; it is fatal." -- Robert Toombs
Well, Toombs was right. It was wrong, it was unnecessary and it was fatal. So it can be accurately said that if any one person is responsible for the destruction of the southron dream of independence, then that person is Jefferson Davis.
