The reason why the Emancipation Proclamation was written was because Lincoln believed slavery was wrong. One of the questions often asked is why it only covered those of the rebelling states. The reason involved legalities. He did not have the authority to issue such a decree on states that were not seceeding.
Although the purpose of the Emancipation Proclamation, in addition to freeing slaves, was to help the war effort, it did have negative consequences on the Union's cause. Many in the North did not support emancipation. Although abolitionist sentiments were high, most, including Lincoln, wanted gradual emancipation.
