I think we want a leader who is logical and empathetic. A completely empathetic leader might not be able to make the 'tough' decisions that come with war, but on the same token a completely logical leader would mostly likely not make a decision that would be considered 'heroic' if it was not a logical decision. The decision by President Truman to drop the bomb on Nagasaki and Hiroshima could potential be seen as logical and empathetic. Logical, because it seemed to be the quickest way to end the war and empathetic, because it would, statistically, save more lives than it destroyed.
