Wrong. Booth was above all, a white supremacist. He had sympathy with the Confederacy, although not nearly enough to make him stop his lucrative acting career to wear a gray uniform. Above all, he feared and hated the idea of free blacks. His earlier bizarre conspiracy, which fell through, was a scheme to kidnap Lincoln. It was not until Lincoln called for voting rights for blacks in a speech in Washington on April 11, 1865 that Booth vowed to kill Lincoln. He kept his promise 2 days later.
