Revenge & Redemption and Deception are common themes in all his films.
Mr Orange attempting to redeem himself by confessing who he is, and Mr White killing him as revenge.
Kill Bill, obviously.
Pulp Fiction. Butch redeeming himself by saving Marcellus and Marcellus deciding not to continue with his wanting of revenge for Butch lying and stealing from him. Jules redeeming himself at the end of the film.
What I mean by deception is that his characters tend to put on some ind of masquerade or performance, pretending to be someone they are not in order to get what they want. Whether that's all the characters in the hteful eight, Mr orange being an undercover cop, Jules putting on a dominant, dramatic act in order to interrogate his victims, Beatrix Kiddo putting on the act of being a normal person despite being a 'natural born killer' as Bill says with his analogy about superman being an alien but having to masquerade as a normal person to fit in, Hans Landa putting on a polite, friendly act to get into the head of whoever he is interrogating, the basterds pretending to be german soldiors in the basement and also pretending to be italian filmmakers to infiltrate security and also Django and Shultz pretending to be mandingo buyers in order to get into candieland and get Djangos wife.
