In summary, my story is set in the 1800's and is about a group of slaves who want to kill the prince to destroy the British empire and get freedom and justice. What they want is understandable, but killing the prince is obviously wrong. The 'heroes' or MCs want to stop the killing, which is understandable, but they're all white save one slave who has realized the assassination is wrong. Obviously the heroes are going to win and the majority of them being white and its increasingly likely the black person who's helping them is going to die, what I'm worried about is my story being perceived as Racist. Also, would it be right for one of my characters to use a racial slurr?
