Interesting way to go about a revenge arc
The perpetrator sets up his own downfall, and two men who have spent their entire lives on two vastly different courses that makes them perfect for the roles they now take, seek to destroy this man, knowing he is also possessed by someone they care for, in their own way, and have his full consent and permission to, psychologically speaking, kick his dick in
All while told from the perspective of the perpetrator, showcasing both a way to be empathetic towards him, while also how irredeemable he is.
Thats a lot to keep straight in your own head as a reader, can't imagine how the author is managing to do it
