It was that simple under, Lincoln. Lincoln jailed dissenters and members of the press, and did all sorts of war crimes against both native Americans and Southern Civilians. Please see Roswell Mill women who were put into slavery up North never to return home, or the 38 Native Americans he mass hanged. He made many white supremacist statements, but he gets a pass by some whites because his armies ended slavery. Lincoln had war powers, and used them often.
