Absolutely. It is for reasons such as these that Lysander Spooner, the great legal philosopher of the abolitionists, denounced their claims to have abolished slavery and saved the union as a "sham" and a "fraud." The abolition of slavery that Spooner spent his life seeking was attained after the war. Yet he denounced it because it was so sinfully achieved and by such tyrannical means. That speaks volumes about those who claim The Lincoln was a morally guided emancipator and friend of liberty.
Looks like Spooner was an idiot.
