It's pretty common knowledge.
On the evening of April 11, the president stood on the White House balcony and delivered a speech to a small group gathered on the lawn. Two days earlier, Robert E. Lee had surrendered the Army of Northern Virginia at Appomattox Court House, and after four long years of struggle it had become clear that the Union cause would emerge from the war victorious. Lincoln’s speech that evening outlined some of his ideas about reconstructing the nation and bringing the defeated Confederate states back into the Union. Lincoln also indicated a wish to extend the franchise to some African-Americans—at the very least, those who had fought in the Union ranks during the war—and expressed a desire that the southern states would extend the vote to literate blacks, as well. Booth stood in the audience for the speech, and this notion seems to have amplified his rage at Lincoln. “That means nigger citizenship,” he told Lewis Powell, one of his band of conspirators. “Now, by God, I’ll put him through. That is the last speech he will ever make.”Source: http://teachinghistory.org/history-content/ask-a-historian/24242
I believe that establishes your point to a reasonable degree, though it does not establish it as the sole reason. What Boothe said after he had shot Lincoln cannot be dismissed. Perhaps Boothe regarded this move by Lincoln as "Tyrannical".
Given the mentality of the time, It is likely that he did.
