1. "in vain" means without reason. "shall not have died in vain" is a phrase from the Gettysburg Address where Lincoln was dedicating a cemetery. "That these dead shall not have died in vain" meant that the Union soldiers who died at Gettysburg would have died for a noble purpose if the North won and the Union stayed together. "shall not have died to no purpose" in other words. 2. shouldn't have died in anger
