c. booth supported the confederacy.
d. booth wanted to be a union soldier.

Your answer would be C). Booth supported the confederacy. The reason why this would be your answer because John Booth supported the confederacy and didn't want it to go away. Booth was very disappointed about the fact that the confederacy lost the war and that slavery was going to be abolished completely. The confederacy was the confederate states in the South, which were the states that were for slavery. Booth was for slavery and supported slavery, he was disappointed that something that he liked was going to go away because of a President. Because of this, he focused all of his anger in President Lincoln since he was the one that signed the law to abolish slavery. And as soon as he noticed that Lincoln was going to For'd Theater, he made his move.
