We here highly resolve that these dead shall not have died in vain.

~ Abraham Lincoln (1809-02-12 1865-04-15 age:56) Gettysburg Address

In the civil war Americans killed 620,000 fellow Americans. Lincoln considers this a sacrifice for a higher good rather than mass insanity. Consider what would have happened had Lincoln negotiated with the south, or let the south leave without bloodshed as Canada would do if Québec seceded. With a nearby slave-free country to escape too, slave owners would be bled dry by having their expensive slaves escape. The war was mainly over taxation. It is ridiculous to murder your brother over a dispute about tax rates. Lincoln was an asshole to go to war over something so trivial. If a bumbling idiot goes on stage during war, he is guaranteed to be painted as a hero after the war ends.
