I'm sure we have all noticed; Maddy lost Izuna. Sasuke lost Itachi. The difference being that sasuke was Itachis younger brother and Maddy was Izuna's older brother. When Sasuke found out Itachi was actually a villanized hero, he decided to take revenge on konoha although Itachi told him not to. When Izuna died Maddy actually listened to his fellow clansmen(Instead of izuna who told him not to trust the senju) and joined forces with his frienemy, begrudgingly.
But Maddy felt slighted by his clan (especially since Izuna died trying to protect the uchiha name) and felt his brother died in vain and so it sent him on revenge seeking rampage(Of course the curse of hatred and the tablet was the cherry on top). So basically Maddy's story is Sasuke's story, except slightly different choices were made, sasuke like Izuna decided to fight on behalf of his clan in the end, while maddy decided to detach himself from the uchiha name. So basically, Sasuke is izuna should he have lived and Itachi is maddy, except he actually made horrid decisions for the greater good rather than for his own selfish reasons. Kishi you sly devil.
