Jefferson Davis didn't control the fighting. Abraham Lincoln controlled the bloodshed. He could have stopped it at any time he wished. He just thought it was worth killing so many people to reestablish financial control over the South.
He couldn't allow them to compete financially with the Empire City. Carthage had to be destroyed so that Rome could rule without challenge. Rome has ruled ever since.
Sure he did. He started it, he could have stopped it. Or not started it to begin with.
This analogy is even worse. You suck at this!
