Yang Guifei was a constort of Emperor Xuanzong of the Tang Dynasty (the first one, there's another Emperor Xuanzong of Tang much later but he has nothing to do with this.) She used her position to get her family member jobs in the goverment which caused alot of problems for the Tang so she was order to end her own life.
Charlotte Corday was a revolutionary during the French Revolution, but she was a sympathizer or part of the Girondins (the moderates who wanted a peaceful transfer) and opposed the Jacobins (the radicals who were guillotining everyone.) She was the assassin of Jean-Paul Marat, a Jacobin propagandist.
I'm going with Corday. Yang just seems like a fu** up. Corday actually killed a guy. I do find it funny the we have 2 people on opposite political sides in a tournament and they don't fight each other.
