Lincoln was right in thinking that “deliberate” would be better than “hurried” when advising the South about secession. Lincoln was right about thinking deliberate rather than hurried because if the South thought in a hurried manner they would make the wrong choices instead of the right ones. Moreover, it was better for the South to think in a slow manner and think about what they were going to get themselves into. Such as, going to war for the fugitive of slave laws, if the South were to hurry they would make the decision to go to war and risk losing their slaves rather than thinking about the bigger picture and leaving the situation alone so the South can keep their slaves.
