What would be the underlying goal of reconstruction… punishing the South or reuniting as quickly as possible?

What would be the underlying goal of reconstruction… punishing the South or reuniting as quickly as possible? Which of the three reconstruction plans (Lincoln, Johnson, Congress) is the most appropriate and most doable? Consider in your responses the goals from each side of the battle (North and South), and then make an argument as to which side won the philosophical battlefield of post war America. There is no denying that the North won the war… but did that victory continue into the years after?
