If you had ever bothered to read the Constitution, you wouldn't ask such a damn stupid question. Lincoln had no constitutional power to take "property" from people in areas that were loyal. But he had every constitutional power as Commander in Chief to confiscate whatever property he deemed necessary for the war effort in areas in Rebellion. The rebels claimed slaves as property, used slaves as military laborers and relied on slaves to supply food and munitions for their war effort, and Lincon simply said ok, if they are property, I can take them away from you. And he did.
As to your second question, Lincoln said quite clearly that his only objective in the war was to preserve the Union. He said that if it took freeing all the slaves, he would do it. If it took freeing some, he would do that. The north did not go to war to end slavery in the south. The south did go to war because Lincoln promised to stop the expansion of slavery. Stopping expansion would have eventually destroyed the economics of slavery which required constant expansion to both keep slave prices high and to assure that the rapidly growng slave population didn't literally overwhelm the white population of the south. Expansion provided both new slave markets and a safety valve to keep Dixie from turning into a Haite.
BTW "genius", if you bother to read the EP, which you have obviously never done, you will see that many areas in the south that were under union control (i.e. Federal Courts operating) on Jan. 1, 1863 were also exempted. It wasn't just the border states.
Now I suggest you sit down and do some serious reading before you start calling others uneducated. You are making a damn fool of yourself.
Not according to these gentlemen.
"What was the reason that induced Georgia to take the step of secession? This reason may be summed up in one single proposition. It was a conviction, a deep conviction on the part of Georgia, that a separation from the North-was the only thing that could prevent the abolition of her slavery." -- Speech of Henry Benning to the Virginia Convention
"Gentlemen, I see before me men who have observed all the records of human life, and many, perhaps, who have been chief actors in many of its gravest scenes, and I ask such men if in all their lore of human society they can offer an example like this? South Carolina has 300,000 whites, and 400,000 slaves. These 300,000 whites depend for their whole system of civilization on these 400,000 slaves. Twenty millions of people, with one of the strongest Governments on the face of the earth, decree the extermination of these 400,000 slaves, and then ask, is honor, is interest, is liberty, is right, is justice, is life, worth the struggle?...Gentlemen, I have thus very rapidly endeavored to group before you the causes which have produced the action of the people of South Carolina." -- Speech of John Preston to the Virginia Convention
"History affords no example of a people who changed their government for more just or substantial reasons. Louisiana looks to the formation of a Southern confederacy to preserve the blessings of African slavery, and of the free institutions of the founders of the Federal Union, bequeathed to their posterity." -- Address of George Williamson, Commissioner from Louisiana to the Texas Secession Convention
"But not to be tedious in enumerating the numerous changes for the better, allow me to allude to one other -- though last, not least. The new constitution has put at rest, forever, all the agitating questions relating to our peculiar institution -- African slavery as it exists amongst us -- the proper status of the negro in our form of civilization. This was the immediate cause of the late rupture and present revolution." -- Alexander Stephens
But hey, what did they know?
